GRNERAL DESCRIPTION
The T436416D SDRAM is a high-speed CMOS synchronous DRAM containing 64 Mbits. It is internally configured as 4 Banks of 1M word x 16 DRAM with a synchronous interface (all signals are registered on the positive edge of the clock signal, CLK). Read and write accesses to the 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 a BankActivate command which is then followed by a Read or Write command. The T436416D provides for programmable Read or Write burst lengths of 1, 2, 4, 8, or full page, with a burst termination option. An auto precharge function may be enabled to provide a self-timed row precharge that is initiated at the end of the burst sequence. The refresh functions, either Auto or Self Refresh are easy to use. By having a programmable mode register, the system can choose the most suitable modes to maximize its performance. These devices are well suited for applications requiring high memory bandwidth and particularly well suited to high performance PC applications.

Pin Descriptions (Table 1. Pin Details of T436416D)
Clock: CLK is driven by the system clock. All SDRAM input signals are sampled on the positive edge of CLK. CLK also increments the internal burst counter and controls the output registers. Clock Enable: CKE activates(HIGH) and deactivates(LOW) the CLK signal. If CKE goes low synchronously with clock(set-up and hold time same as other inputs), the internal clock is suspended from the next clock cycle and the state of output and burst address is frozen as long as the CKE remains low. When all banks are in the idle state, deactivating the clock controls the entry to the Power Down and Self Refresh modes. CKE is synchronous except after the device enters Power Down and Self Refresh modes, where CKE becomes asynchronous until exiting the same mode. The input buffers, including CLK, are disabled during Power Down and Self Refresh modes, providing low standby power. Bank Select: BA0,BA1 input select the bank for operation.

Input
Address Inputs: A0-A11 are sampled during the BankActivate command (row address A0-A11) and Read/Write command (column address A0-A7 with A10 defining Auto Precharge) to select one location out of the 1M available in the respective bank. During a Precharge command, A10 is sampled to determine if all banks are to be precharged (A10 = HIGH). The address inputs also provide the opcode during a Mode Register Set command. Chip Select: CS# enables (sampled LOW) and disables (sampled HIGH) the command decoder. All commands are masked when CS# is sampled HIGH. CS# provides for external bank selection on systems with multiple banks. It is considered part of the command code. Row Address Strobe: The RAS# signal defines the operation commands in conjunction with the CAS# and WE# signals and is latched at the positive edges of CLK. When RAS# and CS# are asserted "LOW" and CAS# is asserted "HIGH," either the BankActivate command or the Precharge command is selected by the WE# signal. When the WE# is asserted "HIGH," the BankActivate command is selected and the bank designated by BS is turned on to the active state. When the WE# is asserted "LOW," the Precharge command is selected and the bank designated by BS is switched to the idle state after the precharge operation. Column Address Strobe: The CAS# signal defines the operation commands in conjunction with the RAS# and WE# signals and is latched at the positive edges of CLK. When RAS# is held "HIGH" and CS# is asserted "LOW," the column access is started by asserting CAS# "LOW." Then, the Read or Write command is selected by asserting WE# "LOW" or "HIGH." Write Enable: The WE# signal defines the operation commands in conjunction with the RAS# and CAS# signals and is latched at the positive edges of CLK. The WE# input is used to select the BankActivate or Precharge command and Read or Write command. Data Input/Output Mask: Controls output buffers in read mode and masks Input data in write mode.

Commands
BankActivate (RAS# = "L", CAS# = "H", WE# = "H", BAs = Bank, A0-A11 = Row Address) The BankActivate command activates the idle bank designated by the BA0,1 signals. By latching the row address on A0 to A11 at the time of this command, the selected row access is initiated. The read or write operation in the same bank can occur after a time delay of tRCD(min.) from the time of bank activation. A subsequent BankActivate command to a different row in the same bank can only be issued after the previous active row has been precharged (refer to the following figure). The minimum time interval between successive BankActivate commands to the same bank is defined by tRC(min.). The SDRAM has four internal banks on the same chip and shares part of the internal circuitry to reduce chip area; therefore it restricts the back-to-back activation of the four banks. tRRD(min.) specifies the minimum time required between activating different banks. After this command is used, the Write command and the Block Write command perform the no mask write operation.

2 BankPrecharge command (RAS# = "L", CAS# = "H", WE# = "L", BAs = Bank, A10 = "L", A0-A9 and A11 = Don't care) The BankPrecharge command precharges the bank designated by BA signal. The precharged bank is switched from the active state to the idle state. This command can be asserted anytime after tRAS(min.) is satisfied from the BankActivate command in the desired bank. The maximum time any bank can be active is specified by tRAS(max.). Therefore, the precharge function must be performed in any active bank within tRAS(max.). At the end of precharge, the precharged bank is still in the idle state and is ready to be activated again. PrechargeAll command (RAS# = "L", CAS# = "H", WE# = "L", BAs = Don’t care, A10 = "H", A0-A9 and A11 = Don't care) The PrechargeAll command precharges all banks simultaneously and can be issued even if all banks are not in the active state. All banks are then switched to the idle state. Read command (RAS# = "H", CAS# = "L", WE# = "H", BAs = Bank, A10 = "L", A0-A7 = Column Address) The Read command is used to read a burst of data on consecutive clock cycles from an active row in an active bank. The bank must be active for at least tRCD(min.) before the Read command is issued. During read bursts, the valid data-out element from the starting column address will be available following the CAS# latency after the issue of the Read command. Each subsequent data-out element will be valid by the next positive clock edge (refer to the following figure). The DQs go into high-impedance at the end of the burst unless other command is initiated. The burst length, burst sequence, and CAS# latency are determined by the mode register, which is already programmed. A full-page burst will continue until terminated (at the end of the page it will wrap to column 0 and continue).

Burst Read Operation(Burst Length = 4, CAS# Latency = 2, 3)
The read data appears on the DQs subject to the values on the DQM inputs two clocks earlier (i.e. DQM latency is two clocks for output buffers). A read burst without the auto precharge function may be interrupted by a subsequent Read or Write command to the same bank or the other active bank before the end of the burst length. It may be interrupted by a BankPrecharge/ PrechargeAll command to the same bank too. The interrupt coming from the Read command can occur on any clock cycle following a previous Read command (refer to the following figure).

The DQM inputs are used to avoid I/O contention on the DQ pins when the interrupt comes from a Write command. The DQMs must be asserted (HIGH) at least two clocks prior to the Write command to suppress data-out on the DQ pins. To guarantee the DQ pins against I/O contention, a single cycle with high-impedance on the DQ pins must occur between the last read data and the Write command (refer to the following three figures). If the data output of the burst read occurs at the second clock of the burst write, the DQMs must be asserted (HIGH) at least one clock prior to the Write command to avoid internal bus contention.

5 Read and AutoPrecharge command (RAS# = "H", CAS# = "L", WE# = "H", BAs = Bank, A10 = "H", A0-A7 = Column Address) The Read and AutoPrecharge command automatically performs the precharge operation after the read operation. Once this command is given, any subsequent command cannot occur within a time delay of {tRP(min.) + burst length}. At full-page burst, only the read operation is performed in this command and the auto precharge function is ignored. Write command (RAS# = "H", CAS# = "L", WE# = "L", BAs = Bank, A10 = "L", A0-A7 = Column Address) The Write command is used to write a burst of data on consecutive clock cycles from an active row in an active bank. The bank must be active for at least tRCD(min.) before the Write command is issued. During write bursts, the first valid data-in element will be registered coincident with the Write command. Subsequent data elements will be registered on each successive positive clock edge (refer to the following figure). The DQs remain with high-impedance at the end of the burst unless another command is initiated. The burst length and burst sequence are determined by the mode register, which is already programmed. A full-page burst will continue until terminated (at the end of the page it will wrap to column 0 and continue).

The Mode Register Set command programs the values of CAS# latency, Addressing Mode and Burst Length in the Mode register to make SDRAM useful for a variety of different applications. The default values of the Mode Register after power-up are undefined; therefore this command must be issued at the power-up sequence. The state of pins A0~A9 and A11 in the same cycle is the data written to the mode register. One clock cycle is required to complete the write in the mode register (refer to the following figure). The contents of the mode register can be changed using the same command and the clock cycle requirements during operation as long as all banks are in the idle state.

Burst Stop command (RAS# = "H", CAS# = "H", WE# = "L") The Burst Stop command is used to terminate either fixed-length or full-page bursts. This command is only effective in a read/write burst without the auto precharge function. The terminated read burst ends after a delay equal to the CAS# latency (refer to the following figure). The termination of a write burst is shown in the following figure.

Device Deselect command (CS# = "H") The Device Deselect command disables the command decoder so that the RAS#, CAS#, WE# and Address inputs are ignored, regardless of whether the CLK is enabled. This command is similar to the No Operation command. AutoRefresh command (RAS# = "L", CAS# = "L", WE# = "H",CKE = "H", A11 = “Don‘t care, A0-A9 = Don't care) The AutoRefresh command is used during normal operation of the SDRAM and is analogous to CAS#before-RAS# (CBR) Refresh in conventional DRAMs. This command is non-persistent, so it must be issued each time a refresh is required. The addressing is generated by the internal refresh controller. This makes the address bits a "don't care" during an AutoRefresh command. The internal refresh counter increments automatically on every auto refresh cycle to all of the rows. The refresh operation must be performed 2048 times within 32ms. The time required to complete the auto refresh operation is specified by tRC(min.). To provide the AutoRefresh command, all banks need to be in the idle state and the device must not be in power down mode (CKE is high in the previous cycle). This command must be followed by NOPs until the auto refresh operation is completed. The precharge time requirement, tRP(min), must be met before successive auto refresh operations are performed. SelfRefresh Entry command (RAS# = "L", CAS# = "L", WE# = "H", CKE = "L", A0-A9 = Don't care) The SelfRefresh is another refresh mode available in the SDRAM. It is the preferred refresh mode for data retention and low power operation. Once the SelfRefresh command is registered, all the inputs to the SDRAM become "don't care" with the exception of CKE, which must remain LOW. The refresh addressing and timing is internally generated to reduce power consumption. The SDRAM may remain in SelfRefresh mode for an indefinite period. The SelfRefresh mode is exited by restarting the external clock and then asserting HIGH on CKE (SelfRefresh Exit command). SelfRefresh Exit command This command is used to exit from the SelfRefresh mode. Once this command is registered, NOP or Device Deselect commands must be issued for tRC(min.) because time is required for the completion of any bank currently being internally refreshed. If auto refresh cycles in bursts are performed during normal operation, a burst of 4096 auto refresh cycles should be completed just prior to entering and just after exiting the SelfRefresh mode. Clock Suspend Mode Entry / PowerDown Mode Entry command (CKE = "L") When the SDRAM is operating the burst cycle, the internal CLK is suspended(masked) from the subsequent cycle by issuing this command (asserting CKE "LOW"). The device operation is held intact while CLK is suspended. On the other hand, when all banks are in the idle state, this command performs entry into the PowerDown mode. All input and output buffers (except the CKE buffer) are turned off in the PowerDown mode. The device may not remain in the Clock Suspend or PowerDown state longer than the refresh period (64ms) since the command does not perform any refresh operations. Clock Suspend Mode Exit / PowerDown Mode Exit command (CKE= "H") When the internal CLK has been suspended, the operation of the internal CLK is reinitiated from the subsequent cycle by providing this command (asserting CKE "HIGH"). When the device is in the PowerDown mode, the device exits this mode and all disabled buffers are turned on to the active state. tPDE(min.) is required when the device exits from the PowerDown mode. Any subsequent commands can be issued after one clock cycle from the end of this command. Data Write / Output Enable, Data Mask / Output Disable command (DQM = "L", "H") During a write cycle, the DQM signal functions as a Data Mask and can control every word of the input data. During a read cycle, the DQM functions as the controller of output buffers. DQM is also used for device selection, byte selection and bus control in a memory system.

Transition times are measured between VIH and VIL. Transition(rise and fall) of input signals are in a fixed slope (1 ns). tHZ defines the time in which the outputs achieve the open circuit condition and are not at reference levels. If clock rising time is longer than 1 ns, ( tR / 2 -0.5) ns should be added to the parameter.
10. Assumed input rise and fall time tT ( tR & tF ) = 1 ns If tR or tF is longer than 1 ns, transient time compensation should be considered, i.e., [(tr + tf)/2 - 1] ns should be added to the parameter. 11. Power up Sequence Power up must be performed in the following sequence. 1) Power must be applied to VDD and VDDQ(simultaneously) when all input signals are held "NOP" state and both CKE = "H" and DQM = "H." The CLK signals must be started at the same time. 2) After power-up, a pause of 200us minimum is required. Then, it is recommended that DQM is held "HIGH" (VDD levels) to ensure DQ output is in high impedance. 3) All banks must be precharged. 4) Mode Register Set command must be asserted to initialize the Mode register. 5) A minimum of 2 Auto-Refresh dummy cycles must be required to stabilize the internal circuitry of the device.
