It is organized as 4banks of 4,194,304 x32. The HYNIX H5MS5122DFR series uses a double-data-rate architecture to achieve high-speed operation. The double data rate architecture is essentially a 2n prefetch architecture with an interface designed to transfer two data per clock cycle at the I/O pins. The Hynix H5MS5122DFR Series offers fully synchronous operations referenced to both rising and falling edges of the clock. While all address and control inputs are latched on the rising edges of the CK (Mobile DDR SDRAM operates from a differential clock: the crossing of CK going HIGH and CK going LOW is referred to as the positive edge of CK), data, data strobe and data mask inputs are sampled on both rising and falling edges of it (Input data is registered on both edges of DQS, and output data is referenced to both edges of DQS, as well as to both edges of CK). The data paths are internally pipelined and 2-bit prefetched to achieve high bandwidth. All input voltage levels are compatible with LVCMOS. Read and write accesses to the Low Power DDR SDRAM (Mobile DDR SDRAM) are burst oriented; accesses start at a selected location and continue for a programmed number of locations in a programmed sequence. Accesses begin with the registration of an ACTIVE command, which is then followed by a READ or WRITE command. The address bits registered coincident with the ACTIVE command are used to select the bank and the row to be accessed. The address bits registered coincident with the READ or WRITE command are used to select the bank and the starting column location for the burst access. The Low Power DDR SDRAM (Mobile DDR SDRAM) provides for programmable read or write bursts of 2, 4 or 8 locations. An AUTO PRECHARGE function may be enabled to provide a self-timed row precharge that is initiated at the end of the burst access. As with standard SDRAM, the pipelined and multibank architecture of Low Power DDR SDRAM (Mobile DDR SDRAM) allows for concurrent operation, thereby providing high effective bandwidth by hiding row precharge and activation times. The Low Power DDR SDRAM (Mobile DDR SDRAM) also provides for special programmable Self Refresh options which are Partial Array Self Refresh (full, half, quarter and 1/8 and 1/16 array) and Temperature Compensated Self Refresh. A burst of Read or Write cycles in progress can be interrupted and replaced by a new burst Read or Write command on any cycle (this pipelined design is not restricted by a 2N rule). Only Read bursts in progress with auto precharge disabled can be terminated by a burst terminate command. Burst Terminate command is undefined and should not be used for Read with Autoprecharge enabled and for Write bursts. Rev 1.2 / Jul. 2008 4 11 Mobile DDR SDRAM 512Mbit (16M x 32bit) H5MS5122DFR Series / H5MS5132DFR Series The Hynix H5MS5122DFR series has the special Low Power function of Auto TCSR (Temperature Compensated Self Refresh) to reduce self refresh current consumption. Since an internal temperature sensor is implemented, it enables to automatically adjust refresh rate according to temperature without external EMRS command. Deep Power Down Mode is an additional operating mode for Low Power DDR SDRAM (Mobile DDR SDRAM). This mode can achieve maximum power reduction by removing power to the memory array within Low Power DDR SDRAM (Mobile DDR SDRAM). By using this feature, the system can cut off almost all DRAM power without adding the cost of a power switch and giving up mother-board power-line layout flexibility. All inputs are LVCMOS compatible. Devices will have a VDD and VDDQ supply of 1.8V (nominal).

All address and control input signals are sampled on the crossing of the positive edge of CK and negative edge of CK. Output (read) data is referenced to the crossings of CK and CK (both directions of crossing). Clock Enable: CKE HIGH activates, and CKE LOW deactivates internal clock signals, device input buffers and output drivers. Taking CKE LOW provides PRECHARGE POWER-DOWN and SELF REFRESH operation (all banks idle), or ACTIVE POWER-DOWN (row ACTIVE in any bank). CKE is synchronous for all functions except for SELF REFRESH EXIT, which is achieved asynchronously. Chip Select: CS enables (registered LOW) and disables (registered HIGH) the command decoder. All commands are masked when CS is registered HIGH. CS provides for external bank selection on systems with multiple banks. CS is considered part of the command code. Command Inputs: RAS, CAS and WE (along with CS) define the command being entered Bank Address Inputs: BA0 and BA1 define to which bank an ACTIVE, READ, WRITE or PRECHARGE command is being applied. BA0 and BA1 also determine which mode register is to be loaded during a MODE REGISTER SET command (MRS, EMRS or SRR). Address inputs: Provide the row address for ACTIVE commands, and the column address and AUTO PRECHARGE bit for READ/WRITE commands, to select one location out of the memory array in the respective bank. The address inputs also provide the op-code during a MODE REGISTER SET command. A10 sampled during a PRECHARGE command determines whether the PRECHARGE applies to one bank (A10 LOW) or all banks (A10 HIGH). If only one bank is to be precharged, the bank is selected by BA0, BA1. For 512Mb (x32, Normal page) Row Address: A0 ~ A12, Column Address: A0 ~ A8 For 512Mb (x32, Reduced Page) Row Address: A0 ~ A13, Column Address: A0 ~ A7 Auto-precharge flag: A10 Data Bus: data input / output pin Input Data Mask: DM is an input mask signal for write data. Input data is masked when DM is sampled. HIGH along with that input data during a WRITE access. DM is sampled on both edges of DQS. Data Mask pins include dummy loading internally, to match the DQ and DQS loading. For x32 devices, DM0 corresponds to the data on DQ0-DQ7, DM1 corresponds to the data on DQ8-DQ15, DM2 corresponds to the data on DQ16-DQ23, and DM3 corresponds to the data on DQ24-DQ31. Data Strobe: Output with read data, input with write data. Edge-aligned with read data, center-aligned with write data. Used to capture write data. For x32 device, DQS0 corresponds to the data on DQ0-DQ7, DQS1 corresponds to the data on DQ8-DQ15, DQS2 corresponds to the data on DQ16-DQ23, and DQS3 corresponds to the data on DQ24-DQ31.

Current State Definitions: Idle: The bank has been precharged, and tRP has been met. Row Active: A row in the bank has been activated, and tRCD has been met. No data bursts/accesses and no register accesses are in progress. Read: A READ burst has been initiated, with AUTO PRECHARGE disabled, and has not yet terminated or been terminated. Write: a WRITE burst has been initiated, with AUTO PRECHARGE disabled, and has not yet terminated or been terminated. 8. The following states must not be interrupted by a command issued to the same bank. DESELECT or NOP commands or allowable commands to the other bank should be issued on any clock edge occurring during these states. Allowable commands to the other bank are determined by its current state and Truth Table3, and according to Truth Table 4. Precharging: Starts with the registration of a PRECHARGE command and ends when tRP is met. Once tRP is met, the bank will be in the idle state. Row Activating: Starts with registration of an ACTIVE command and ends when tRCD is met. Once tRCD is met, the bank will be in the ''row active'' state. Read with AP Enabled: Starts with the registration of the READ command with AUTO PRECHARGE enabled and ends when tRP has been met. Once tRP has been met, the bank will be in the idle state. Write with AP Enabled: Starts with registration of a WRITE command with AUTO PRECHARGE enabled and ends when tRP has been met. Once tRP is met, the bank will be in the idle state. 9. The following states must not be interrupted by any executable command; DESELECT or NOP commands must be applied to each positive clock edge during these states. Refreshing: Starts with registration of an AUTO REFRESH command and ends when tRFC is met. Once tRFC is met, the LP DDR will be in an ''all banks idle'' state. Accessing Mode Register: Starts with registration of a MODE REGISTER SET command and ends when tMRD has been met. Once tMRD is met, the LP DDR will be in an ''all banks idle'' state. Precharging All: Starts with the registration of a PRECHARGE ALL command and ends when tRP is met. Once tRP is met, the bank will be in the idle state. 10. Not bank-specific; requires that all banks are idle and no bursts are in progress. 11. Not bank-specific. BURST TERMINATE affects the most recent READ burst, regardless of bank. 12. Requires appropriate DM masking. 13. A WRITE command may be applied after the completion of the READ burst; otherwise, a Burst terminate must be used to end the READ prior to asserting a WRITE command.

The table applies when both CKEn-1 and CKEn are HIGH, and after tXSR or tXP has been met if the previous state was Self Refresh or Power Down. 2. DESELECT and NOP are functionally interchangeable. 3. All states and sequences not shown are illegal or reserved. 4. Current State Definitions: Idle: The bank has been precharged, and tRP has been met. Row Active: A row in the bank has been activated, and tRCD has been met. No data bursts/accesses and no register accesses are in progress. Read: A READ burst has been initiated, with AUTO PRECHARGE disabled, and has not yet terminated or been terminated. Write: a WRITE burst has been initiated, with AUTO PRECHARGE disabled, and has not yet terminated or been terminated. 5. Read with AP enabled and Write with AP enabled: The read with Autoprecharge enabled or Write with Autoprecharge enabled states can be broken into two parts: the access period and the precharge period. For Read with AP, the precharge period is defined as if the same burst was executed with Auto Precharge disabled and then followed with the earliest possible PRECHARGE command that still accesses all the data in the burst. For Write with Auto precharge, the precharge period begins when tWR ends, with tWR measured as if Auto Precharge was disabled. The access period starts with registration of the command and ends where the precharge period (or tRP) begins. During the precharge period, of the Read with Autoprecharge enabled or Write with Autoprecharge enabled states, ACTIVE, PRECHARGE, READ, and WRITE commands to the other bank may be applied; during the access period, only ACTIVE and PRECHARGE commands to the other banks may be applied. In either case, all other related limitations apply (e.g. contention between READ data and WRITE data must be avoided). 6. AUTO REFRESH, SELF REFRESH, and MODE REGISTER SET commands may only be issued when all bank are idle. 7. A BURST TERMINATE command cannot be issued to another bank; it applies to the bank represented by the current state only. 8. READs or WRITEs listed in the Command column include READs and WRITEs with AUTO PRECHARGE enabled and READs and WRITEs with AUTO PRECHARGE disabled. 9. Requires appropriate DM masking. 10. A WRITE command may be applied after the completion of data output, otherwise a BURST TERMINATE command must be issued to end the READ prior to asserting a WRITE command.

Min (tCL, tCH) refers to the smaller of the actual clock low time and the actual clock high time as provided to the device (i.e. this value can be greater than the minimum specification limits for tCL and tCH) 2. tQH = tHP - tQHS, where tHP = minimum half clock period for any given cycle and is defined by clock high or clock low (tCL, tCH). tQHS accounts for 1) the pulse duration distortion of on-chip clock circuits; and 2) the worst case push-out of DQS on one transition followed by the worst case pull-in of DQ on the next transition, both of which are, separately, due to data pin skew and output pattern effects, and p-channel to n-channel variation of the output drivers. 3. The only time that the clock frequency is allowed to change is during clock stop, power-down or self-refresh modes. 4. The transition time for DQ, DM and DQS inputs is measured between VIL(DC) to VIH(AC) for rising input signals, and VIH(DC) to VIL(AC) for falling input signals. 5. DQS, DM and DQ input slew rate is specified to prevent double clocking of data and preserve setup and hold times. Signal transitions through the DC region must be monotonic. 6. Input slew rate ≥ 1.0 V/ns. 7. These parameters guarantee device timing but they are not necessarily tested on each device. 8. The transition time for address and command inputs is measured between VIH and VIL. 9. A CK/CK differential slew rate of 2.0 V/ns is assumed for this parameter. 10. tHZ and tLZ transitions occur in the same access time windows as valid data transitions. These parameters are not referred to a specific voltage level, but specify when the device is no longer driving (HZ), or begins driving (LZ). 11. tDQSQ consists of data pin skew and output pattern effects, and p-channel to n-channel variation of the output drivers for any given cycle. 12. The specific requirement is that DQS be valid (HIGH, LOW, or some point on a valid transition) on or before this CK edge. A valid transition is defined as monotonic and meeting the input slew rate specifications of the device. When no writes were previously in progress on the bus, DQS will be transitioning from Hi-Z to logic LOW. If a previous write was in progress, DQS could be HIGH, LOW, or transitioning from HIGH to LOW at this time, depending on tDQSS. 13. The maximum limit for this parameter is not a device limit. The device operates with a greater value for this parameter, but system performance (bus turnaround) will degrade accordingly. 14. A low level on DQS may be maintained during High-Z states (DQS drivers disabled) by adding a weak pull-down element in the system. It is recommended to turn off the weak pull-down element during read and write bursts (DQS drivers enabled). 15. Speed bin (CL-tRCD-tRP) = 3-3-3 16. Minimum 3CLK of tDAL(= tWR+tRP) is required because it need minimum 2CLK for tWR and minimum 1CLK for tRP. tDAL = (tWR/tCK) + (tRP/tCK): for each of the terms above, if not already an integer, round to the next higher integer. 17. A maximum of eight Refresh commands can be posted to any given Low Power DDR SDRAM (Mobile DDR SDRAM), meaning that the maximum absolute interval between any Refresh command and the next Refresh command is 8*tREFI. 18. All AC parameters are guaranteed by full range of operating voltage and temperature. VDD, VDDQ = 1.7V ~ 1.95V. Temperature = -30oC ~ +85oC.

The Mobile DDR SDRAM is effectively deselected. Operations already in progress are not affected. NO OPERATION The NO OPERATION (NOP) command is used to perform a NOP to a Mobile DDR SDRAM that is selected (CS = Low). This prevents unwanted commands from being registered during idle or wait states. Operations already in progress are not affected. (see to next figure) ACTIVE The Active command is used to activate a row in a particular bank for a subsequent Read or Write access. The value of the BA0,BA1 inputs selects the bank, and the address provided on A0-A13 (only 1KByte page size. If the 2KBytes page size, A0~A12 are provided selects the row. (see to next figure) Before any READ or WRITE commands can be issued to a bank within the Mobile DDR SDRAM, a row in that bank must be opened. This is accomplished via the ACTIVE command, which selects both the bank and the row to be activated. The row remains active until a PRECHARGE (or READ with AUTO PRECHARGE or WRITE with AUTO PRECHARGE) command is issued to the bank. A PRECHARGE (or READ with AUTO PRECHARGE or WRITE with AUTO PRECHARGE) command must be issued before opening a different row in the same bank.

A subsequent ACTIVE command to a different row in the same bank can only be issued after the previous active row has been closed (precharge). The minimum time interval between successive ACTIVE commands to the same bank is defined by tRC. A subsequent ACTIVE command to another bank can be issued while the first bank is being accessed, which results in a reduction of total row-access overhead.

The value of BA0 and BA1 selects the bank and address inputs select the starting column location. The value of A10 determines whether or not auto precharge is used. If auto precharge is selected, the row being accessed will be precharged at the end of the read burst; if auto precharge is not selected, the row will remain open for subsequent access. The valid data-out elements will be available CAS latency after the READ command is issued. The Mobile DDR drives the DQS during read operations. The initial low state of the DQS is known as the read preamble and the last data-out element is coincident with the read postamble. DQS is edge-aligned with read data. Upon completion of a burst, assuming no new READ commands have been initiated, the I/O's will go high-Z. The WRITE command is used to initiate a Burst Write access to an active row. The value of BA0, BA1 selects the bank and address inputs select the starting column location. The value of A10 determines whether or not auto precharge is used.If auto precharge is selected, the row being accessed will be precharged at the end of the write burst; if auto precharge is not selected, the row will remain open for subsequent access. Input data appearing on the data bus, is written to the memory array subject to the DM input logic level appearing coincident with the data. If a given DM signal is registered low, the corresponding data will be written to the memory; if the DM signal is registered high, the corresponding data-inputs will be ignored, and a write will not be executed to that byte/column location. The memory controller drives the DQS during write operations. The initial low state of the DQS is known as the write preamble and the low state following the last data-in element is write postamble. Upon completion of a burst, assuming no new commands have been initiated, the I/O's will stay high-Z and any additional input data will be ignored.

Another command to the same bank (or banks) being precharged must not be issued until the precharge time (tRP) is completed. If one bank is to be precharged, the particular bank address needs to be specified. If all banks are to be precharged, A10 should be set high along with the PRECHARGE command. If A10 is high, BA0 and BA1 are ignored. A PRECHARGE command will be treated as a NOP if there is no open row in that bank, or if the previously open row is already in the process of precharging. The below figure shows in case of 1KByte page size. If the page size is 2KByte, A0~A9, A11 and A12 are provided.

This is accomplished by using A10 (A10=high), to enable auto precharge in conjunction with a specific Read or Write command. This precharges the bank/row after the Read or Write burst is complete. Auto precharge is non persistent, so it should be enabled with a Read or Write command each time auto precharge is desired. Auto precharge ensures that a precharge is initiated at the earliest valid stage within a burst. The user must not issue another command to the same bank until the precharge time (tRP) is completed.

Each refresh is generated in one of two ways: by an explicit AUTO REFRESH command, or by an internally timed event in SELF REFRESH mode: - AUTO REFRESH. This command is used during normal operation of the Mobile DDR. It is non persistent, so must be issued each time a refresh is required. The refresh addressing is generated by the internal refresh controller.The Mobile DDR requires AUTO REFRESH commands at an average periodic interval of tREFI. To allow for improved efficiency in scheduling and switching between tasks, some flexibility in the absolute refresh interval is provided. A maximum of eight AUTO REFRESH commands can be posted to any given Mobile DDR, and the maximum absolute interval between any AUTO REFRESH command and the next AUTO REFRESH command is 8*tREFI. -SELF REFRESH. This state retains data in the Mobile DDR, even if the rest of the system is powered down (even without external clocking). Note refresh interval timing while in Self Refresh mode is scheduled internally in the Mobile DDR and may vary and may not meet tREFI time. ''Don't Care'' except CKE, which must remain low. An internal refresh cycle is scheduled on Self Refresh entry. The procedure for exiting Self Refresh mode requires a series of commands. First clock must be stable before CKE going high. NOP commands should be issued for the duration of the refresh exit time (tXSR), because time is required for the completion of any internal refresh in progress. The use of SELF REFRESH mode introduces the possibility that an internally timed event can be missed when CKE is raised for exit from self refresh mode. Upon exit from SELF REFRESH an extra AUTO REFRESH command is recommended. In the self refresh mode, two additional power-saving options exist. They are Temperature Compensated Self Refresh and Partial Array Self Refresh and are described in the Extended Mode Register section. The Self Refresh command is used to retain cell data in the Mobile SDRAM. In the Self Refresh mode, the Mobile SDRAM operates refresh cycle asynchronously. The Self Refresh command is initiated like an Auto Refresh command except CKE is disabled (Low). The Mobile DDR can accomplish an special Self Refresh operation by the specific modes (PASR) programmed in extended mode registers. The Mobile DDR can control the refresh rate automatically by the temperature value of Auto TCSR (Temperature Compensated Self Refresh) to reduce self refresh current and select the memory array to be refreshed by the value of PASR (Partial Array Self Refresh). The Mobile DDR can reduce the self refresh current(IDD6) by using these two modes. The figure of next page shows in case of 1KByte page size. If the page size is 2KByte, A0~A12 are provided.

BURST TYPE Accesses within a given burst may be programmed to be either sequential or interleaved. CAS LATENCY The CAS latency is the delay between the registration of a READ command and the availability of the first piece of output data. If a READ command is registered at a clock edge n and the latency is 3 clocks, the first data element will be valid at n + 2tCK + tAC. If a READ command is registered at a clock edge n and the latency is 2 clocks, the first data element will be valid at n + tCK + tAC.

The Extended Mode Register is programmed via the MODE REGISTER SET command (with BA1=1 and BA0=0) and will retain the stored information until it is reprogrammed, the device is put in Deep Power-Down mode, or the device loses power. The Extended Mode Register should be loaded when all Banks are idle and no bursts are in progress, and subsequent operation should only be initiated after tMRD. Violating these requirements will result in unspecified operation. The Extended Mode Register is written by asserting low on CS, RAS, CAS, WE and high on BA0. The state of address pins A0 ~ A13(or A12 which depands on page size) and BA1 in the same cycle as CS, RAS, CAS and WE going low are written in the extended mode register. The Extended Mode Register must be loaded when all banks are idle and no bursts are in progress, and the controller must wait the specified time before initiating any subsequent operation. Violating either of these requirements will result in unspecified operation. This register includes the selection of partial array to be refreshed (full array, half array, quarter array, etc.). The extended mode register set must be done before any activate command after the power up sequence. Any contents of the mode register be altered by re-programming the mode register through the execution of extended mode register set command. PARTIAL ARRAY SELF REFRESH (PASR) With PASR, the self refresh may be restricted to a variable portion of the total array. The whole array (default), 1/2 array, 1/4 array, 1/8 array or 1/16 array could be selected. DRIVE STRENGTH (DS) The drive strength could be set to full or half via address bits A5, A6 and A7. The half drive strength is intended for lighter loads or point-to-point environments.

If power down occurs when all banks are idle, it is Precharge Power Down. If Power down occurs when one or more banks are Active, it is referred to as Active power down. The device cannot stay in this mode for longer than the refresh requirements of the device, without losing data. The power down state is exited by setting CKE high while issuing a Device Deselect or NOP command. A valid command can be issued after tXP. For Clock stop during power down mode, please refer to the Clock Stop subsection in Operation section of this datasheet. NOTE: This case shows CKE low coincident with NO OPERATION. Alternately POWER DOWN entry can be achieved with CKE low coincident with Device DESELECT. DEEP POWER DOWN The Deep Power Down (DPD) mode enables very low standby currents. All internal voltage generators inside the Mobile DDR SDRAM are stopped and all memory data is lost in this mode. All the information in the Mode Register and the Extended Mode Register is lost. Next Figure, DEEP POWER DOWN COMMAND shows the DEEP POWER DOWN command All banks must be in idle state with no activity on the data bus prior to entering the DPD mode. While in this state, CKE must be held in a constant low state. To exit the DPD mode, CKE is taken high after the clock is stable and NOP command must be maintained for at least 200 us. After 200 us a complete re-initialization routing is required following steps 4 through 11 as defined in POWERUP and INITIALIZATION SEQUENCES. The below figure shows in case of 1KByte page size.

Rev 1.2 / Jul. 2008 57 11 Mobile DDR SDRAM 512Mbit (16M x 32bit) H5MS5122DFR Series / H5MS5132DFR Series Clock Stop Mode Clock stop mode is a feature supported by Mobile DDR SDRAM devices. It reduces clock-related power consumption during idle periods of the device. Conditions: the Mobile DDR SDRAM supports clock stop in case: ● The last access command (ACTIVE, READ, WRITE, PRECHARGE, AUTO REFRESH or MODE REGISTER SET) has executed to completion, including any data-out during read bursts; the number of required clock pulses per access command depends on the device's AC timing parameters and the clock frequency; ● The related timing condition (tRCD, tWR, tRP, tRFC, tMRD) has been met; ● CKE is held HIGH. When all conditions have been met, the device is either in ''idle'' or ''row active'' state, and clock stop mode may be entered with CK held LOW and CK held HIGH. Clock stop mode is exited when the clock is restarted. NOPs command have to be issued for at least one clock cycle before the next access command may be applied. Additional clock pulses might be required depending on the system characteristics. Figure1 illustrates the clock stop mode: ● Initially the device is in clock stop mode; ● The clock is restarted with the rising edge of T0 and a NOP on the command inputs; ● With T1 a valid access command is latched; this command is followed by NOP commands in order to allow for clock stop as soon as this access command has completed; ● Tn is the last clock pulse required by the access command latched with T1. ● The timing condition of this access command is met with the completion of Tn; therefore Tn is the last clock pulse required by this command and the clock is then stopped.

Data masking is only available in the write cycle for Mobile DDR SDRAM. Data masking is available during write, but data masking during read is not available. DM command masks burst write data with reference to data strobe signal and it is not related with read data. DM command can be initiated at both the rising edge and the falling edge of the DQS. DM latency for write operation is zero. For x32 data I/O, Mobile DDR SDRAM is equipped with DM0, DM1, DM2 and DM3 which control DQ0~DQ7, DQ8~DQ15, DQ16~DQ23 and DQ24~DQ31 respectively.

Operations procedures other thank those specified may result in undefined operation. If there is any interruption to the device power, the initialization routine should be followed. The steps to be followed for device initialization are listed below. ● Step1: Provide power, the device core power (VDD) and the device I/O power (VDDQ) must be brought up simulta- neously to prevent device latch-up. Although not required, it is recommended that VDD and VDDQ are from the same power source. Also assert and hold CLOCK ENABLE (CKE) to a LVCMOS logic high level. ● Step 2: Once the system has established consistent device power and CKE is driven high, it is safe to apply stable clock. ● Step 3: There must be at least 200us of valid clocks before any command may be given to the DRAM. During this time NOP or DESELECT commands must be issued on the command bus. ● Step 4: Issue a PRECHARGE ALL command. ● Step 5: Provide NOPs or DESELECT commands for at least tRP time. ● Step 6: Issue an AUTO REFRESH command followed by NOPs or DESELECT command for at least tRFC time. Issue the second AUTO REFRESH command followed by NOPs or DESELECT command for at least tRFC time. Note as part of the initialization sequence there must be two auto refresh commands issued. The typical flow is to issue them at Step 6, but they may also be issued between steps 10 and 11. ● Step 7: Using the MRS command, load the base mode register. Set the desired operating modes. ● Step 8: Provide NOPs or DESELECT commands for at least tMRD time. ● Step 9: Using the MRS command, program the extended mode register for the desired operating modes. Note the order of the base and extended mode register programming is not important. ● Step 10: Provide NOP or DESELCT commands for at least tMRD time. ● Step 11: The DRAM has been properly initialized and is ready for any valid command.
