This synchronous device achieves high speed double-data-rate transfer rates of up to 1600Mb/sec/pin (DDR31600) for general applications. The chip is designed to comply with the following key DDR3 SDRAM features such as posted CAS, Programmable CWL, Internal (Self) Calibration, On Die Termination using ODT pin and Asynchronous Reset . All of the control and address inputs are synchronized with a pair of externally supplied differential clocks. Inputs are latched at the crosspoint of differential clocks (CK rising and CK falling). All I/Os are synchronized with a pair of bidirectional strobes (DQS and DQS) in a source synchronous fashion. The address bus is used to convey row, column, and bank address information in a RAS/CAS multiplexing style. The DDR3 device operates with a single 1.35V(1.28V~1.45V) or 1.5V(1.425V~1.575V) power supply and 1.35V(1.28V~1.45V) or 1.5V(1.425V~1.575V).

Input/Output Functional Description [ Table 3 ] Input/Output function description Symbol CK, CK Clock: CK and CK are differential clock inputs. 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 Clock Enable: CKE HIGH activates, and CKE Low deactivates, internal clock signals and 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 asynchronous for self refresh exit. After VREFCA has become stable during the power on and initialization sequence, it must be maintained during all operations (including SelfRefresh). CKE must be maintained high throughout read and write accesses. Input buffers, excluding CK, CK, ODT and CKE are disabled during power-down. Input buffers, excluding CKE, are disabled during Self -Refresh. Chip Select: All commands are masked when CS is registered HIGH. CS provides for external Rank selection on systems with multiple Ranks. CS is considered part of the command code. On Die Termination: ODT (registered HIGH) enables termination resistance internal to the DDR3 SDRAM. When enabled, ODT is only applied to each DQ, DQS, DQS and DM/TDQS, NU/TDQS (When TDQS is enabled via Mode Register A11=1 in MR1) signal for x8 configurations. The ODT pin will be ignored if the Mode Register (MR1) is programmed to disable ODT. Command Inputs: RAS, CAS and WE (along with CS) define the command being entered. Input Data Mask: DM is an input mask signal for write data. Input data is masked when DM is sampled HIGH coincident with that input data during a Write access. DM is sampled on both edges of DQS. For x8 device, the function of DM or TDQS/TDQS is enabled by Mode Register A11 setting in MR1. Bank Address Inputs: BA0 - BA2 define to which bank an Active, Read, Write or Precharge command is being applied. Bank address also determines if the mode register or extended mode register is to be accessed during a MRS cycle. Address Inputs: Provided the row address for Active commands and the column address for Read/Write commands to select one location out of the memory array in the respective bank. (A10/AP and A12/BC have additional functions, see below) The address inputs also provide the op-code during Mode Register Set commands. Autoprecharge: A10 is sampled during Read/Write commands to determine whether Autoprecharge should be performed to the accessed bank after the Read/Write operation. (HIGH:Autoprecharge; LOW: No Autoprecharge) A10 is sampled during a Precharge command to determine 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 bank addresses. Burst Chop:A12 is sampled during Read and Write commands to determine if burst chop(on-the-fly) will be performed. (HIGH : no burst chop, LOW : burst chopped). See command truth table for details Active Low Asynchronous Reset: Reset is active when RESET is LOW, and inactive when RESET is HIGH. RESET must be HIGH during normal operation. RESET is a CMOS rail to rail signal with DC high and low at 80% and 20% of VDD, i.e. Data Input/ Output: Bi-directional data bus. Data Strobe: Output with read data, input with write data. Edge-aligned with read data, centered in write data. For the x16, DQSL: corresponds to the data on DQL0-DQL7; DQSU corresponds to the data on DQU0-DQU7. The data strobe DQS, DQSL and DQSU are paired with differential signals DQS, DQSL and DQSU, respectively, to provide differential pair signaling to the system during reads and writes. DDR3 SDRAM supports differential data strobe only and does not support single-ended. Termination Data Strobe: TDQS/TDQS is applicable for X8 DRAMs only. When enabled via Mode Register A11=1 in MR1, DRAM will enable the same termination resistance function on TDQS/TDQS that is applied to DQS/DQS. When disabled via mode register A11=0 in MR1, DM/TDQS will provide the data mask function and TDQS is not used. x4/ x16 DRAMs must disable the TDQS function via mode register A11=0 in MR1. No Connect: No internal electrical connection is present.

Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 2. Storage Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to JESD51-2 standard. 3. VDD and VDDQ must be within 300mV of each other at all times;and VREF must be not greater than 0.6 x VDDQ, When VDD and VDDQ are less than 500mV; VREF may be equal to or less than 300mV. 6.2 DRAM Component Operating Temperature Range [ Table 5 ] Temperature Range Symbol TOPER Parameter Operating Temperature Range rating 0 to 95 Unit °C NOTE 1, 2, 3 NOTE : 1. Operating Temperature TOPER is the case surface temperature on the center/top side of the DRAM. For measurement conditions, please refer to the JEDEC document JESD51-2. 2. The Normal Temperature Range specifies the temperatures where all DRAM specifications will be supported. During operation, the DRAM case temperature must be maintained between 0-85°C under all operating conditions 3. Some applications require operation of the Extended Temperature Range between 85°C and 95°C case temperature. Full specifications are guaranteed in this range, but the following additional conditions apply: a) Refresh commands must be doubled in frequency, therefore reducing the refresh interval tREFI to 3.9us. b) If Self-Refresh operation is required in the Extended Temperature Range, then it is mandatory to either use the Manual Self-Refresh mode with Extended Temperature Range capability (MR2 A6 = 0b and MR2 A7 = 1b), in this case IDD6 current can be increased around 10~20% than normal Temperature range. 7.

It shows a valid reference voltage VREF(t) as a function of time. (VREF stands for VREFCA and VREFDQ likewise). VREF(DC) is the linear average of VREF(t) over a very long period of time (e.g. 1 sec). This average has to meet the min/max requirement in Table 7 on page 12. Furthermore VREF(t) may temporarily deviate from VREF(DC) by no more than ± 1% VDD. voltage VDD VSS time Figure 1. Illustration of VREF(DC) tolerance and VREF ac-noise limits The voltage levels for setup and hold time measurements VIH(AC), VIH(DC), VIL(AC) and VIL(DC) are dependent on VREF. "VREF" shall be understood as VREF(DC), as defined in Figure 1 . This clarifies, that dc-variations of VREF affect the absolute voltage a signal has to reach to achieve a valid high or low level and therefore the time to which setup and hold is measured. System timing and voltage budgets need to account for VREF(DC) deviations from the optimum position within the data-eye of the input signals. This also clarifies that the DRAM setup/hold specification and derating values need to include time and voltage associated with VREF ac-noise. Timing and voltage effects due to ac-noise on VREF up to the specified limit (+/-1% of VDD) are included in DRAM timings and their associated deratings. - 14 - K4B2G0446D K4B2G0846D datasheet tDVAC VIH.DIFF.AC.MIN Differential Input Voltage (i.e. DQS-DQS, CK-CK) Rev. 1.01 DDR3L SDRAM 8.3 AC & DC Logic Input Levels for Differential Signals 8.3.1 Differential signals definition VIH.DIFF.MIN 0.0 half cycle VIL.DIFF.MAX VIL.DIFF.AC.MAX tDVAC time Figure 2.

CK and CK have to approximately reach VSEHmin / VSELmax [approximately equal to the ac-levels { VIH(AC) / VIL(AC)} for ADD/CMD signals] in every half-cycle. DQS, DQSL, DQSU, DQS, DQSL have to reach VSEHmin / VSELmax [approximately the ac-levels { VIH(AC) / VIL(AC)} for DQ signals] in every half-cycle proceeding and following a valid transition. Note that the applicable ac-levels for ADD/CMD and DQ’s might be different per speed-bin etc. E.g. if VIH150(AC)/VIL150(AC) is used for ADD/CMD signals, then these ac-levels apply also for the single-ended signals CK and CK .

Single-ended requirement for differential signals VSS or VSSQ Note that while ADD/CMD and DQ signal requirements are with respect to VREF, the single-ended components of differential signals have a requirement with respect to VDD/2; this is nominally the same. The transition of single-ended signals through the ac-levels is used to measure setup time. For singleended components of differential signals the requirement to reach VSELmax, VSEHmin has no bearing on timing, but adds a restriction on the common mode characteristics of these signals.

IDD Current Measure Method 10.1 IDD Measurement Conditions In this chapter, IDD and IDDQ measurement conditions such as test load and patterns are defined. Figure 19 shows the setup and test load for IDD and IDDQ measurements. - IDD currents (such as IDD0, IDD1, IDD2N, IDD2NT, IDD2P0, IDD2P1, IDD2Q, IDD3N, IDD3P, IDD4R, IDD4W, IDD5B, IDD6, IDD6ET, IDD6TC and IDD7) are measured as time-averaged currents with all VDD balls of the DDR3 SDRAM under test tied together. Any IDDQ current is not included in IDD currents. - IDDQ currents (such as IDDQ2NT and IDDQ4R) are measured as time-averaged currents with all VDDQ balls of the DDR3 SDRAM under test tied together. Any IDD current is not included in IDDQ currents. Attention : IDDQ values cannot be directly used to calculate IO power of the DDR3 SDRAM. They can be used to support correlation of simulated IO power to actual IO power as outlined in Figure 20. In DRAM module application, IDDQ cannot be measured separately since VDD and VDDQ are using one merged-power layer in Module PCB. For IDD and IDDQ measurements, the following definitions apply : - "0" and "LOW" is defined as VIN = VIHAC(min). - "FLOATING" is defined as inputs are VREF = VDD / 2. - "Timing used for IDD and IDDQ Measured - Loop Patterns" are provided in Table 32 - "Basic IDD and IDDQ Measurement Conditions" are described in Table 33 - Detailed IDD and IDDQ Measurement-Loop Patterns are described in Table 32 on page 31 through Table 39. - IDD Measurements are done after properly initializing the DDR3 SDRAM. This includes but is not limited to setting RON = RZQ/7 (34 Ohm in MR1); Qoff = 0B (Output Buffer enabled in MR1); RTT_Nom = RZQ/6 (40 Ohm in MR1); RTT_Wr = RZQ/2 (120 Ohm in MR2); TDQS Feature disabled in MR1 - Attention : The IDD and IDDQ Measurement-Loop Patterns need to be executed at least one time before actual IDD or IDDQ measurement is started. - Define D = {CS, RAS, CAS, WE} := {HIGH, LOW, LOW, LOW} - Define D = {CS, RAS, CAS, WE} := {HIGH, HIGH, HIGH, HIGH} - RESET Stable time is : During a Cold Bood RESET (Initialization), current reading is valid once power is stable and RESET has been LOW for 1ms; During Warm Boot RESET(while operating), current reading is valid after RESET has been LOW for 200ns + tRFC [ Table 32 ] Timing used for IDD and IDDQ Measured - Loop Patterns Parameter tCKmin(IDD) CL(IDD) tRCDmin(IDD) tRCmin(IDD) tRASmin(IDD) tRPmin(IDD) tFAW(IDD) tRRD(IDD) x4/x8 x16 x4/x8 x16 Bin DDR3-800 6-6-6 2.5 6 6 21 15 6 16 20 4 4 36 44 64 120 140 DDR3-1066 7-7-7 1.875 7 7 27 20 7 20 27 4 6 48 59 86 160 187 DDR3-1333 9-9-9 1.5 9 9 33 24 9 20 30 4 5 60 74 107 200 234 DDR3-1600 11-11-11 1.25 11 11 39 28 11 24 32 5 6 72 88 128 240 280 Unit ns nCK nCK nCK nCK nCK nCK nCK nCK nCK nCK nCK nCK nCK nCK tRFC(IDD) - 512Mb tRFC(IDD) - 1Gb tRFC(IDD) - 2Gb tRFC(IDD) - 4Gb tRFC(IDD) - 8Gb - 32 - K4B2G0446D K4B2G0846D datasheet IDD IDDQ Rev. 1.01 DDR3L SDRAM VDD RESET CK/CK CKE CS RAS, CAS, WE A, BA ODT ZQ VDDQ DQS, DQS DQ, DM, TDQS, TDQS RTT = 25 Ohm VDDQ/2 VSS VSSQ [NOTE : DIMM level Output test load condition may be different from above] Figure 19.

Electrical Characteristics and AC timing for DDR3-800 to DDR3-1600 13.1 Clock Specification The jitter specified is a random jitter meeting a Gaussian distribution. Input clocks violating the min/max values may result in malfunction of the DDR3 SDRAM device. 13.1.1 Definition for tCK(avg) tCK(avg) is calculated as the average clock period across any consecutive 200 cycle window, where each clock period is calculated from rising edge to rising edge. N ∑ j=1 tCKj N N=200 13.1.2 Definition for tCK(abs) tCK(abs) is defind as the absolute clock period, as measured from one rising edge to the next consecutive rising edge. tCK(abs) is not subject to production test. 13.1.3 Definition for tCH(avg) and tCL(avg) tCH(avg) is defined as the average high pulse width, as calculated across any consecutive 200 high pulses: tCL(avg) is defined as the average low pulse width, as calculated across any consecutive 200 low pulses: N N ∑ j=1 tCHj N x tCK(avg) N=200 ∑ j=1 tCLj N x tCK(avg) N=200 13.1.4 Definition for note for tJIT(per), tJIT(per, Ick) tJIT(per) is defined as the largest deviation of any single tCK from tCK(avg). tJIT(per) = min/max of {tCKi-tCK(avg) where i=1 to 200} tJIT(per) defines the single period jitter when the DLL is already locked. tJIT(per,lck) uses the same definition for single period jitter, during the DLL locking period only. tJIT(per) and tJIT(per,lck) are not subject to production test. 13.1.5 Definition for tJIT(cc), tJIT(cc, Ick) tJIT(cc) is defined as the absolute difference in clock period between two consecutive clock cycles: tJIT(cc) = Max of {tCKi+1-tCKi} tJIT(cc) defines the cycle to cycle jitter when the DLL is already locked. tJIT(cc,lck) uses the same definition for cycle to cycle jitter, during the DLL locking period only. tJIT(cc) and tJIT(cc,lck) are not subject to production test. 13.1.6 Definition for tERR(nper) tERR is defined as the cumulative error across n multiple consecutive cycles from tCK(avg). tERR is not subject to production test. - 43 - K4B2G0446D K4B2G0846D datasheet Symbol tRFC tREFI 0 °C ≤ TCASE ≤ 85°C 85 °C < TCASE ≤ 95°C 1Gb 110 7.8 3.9 2Gb 160 7.8 3.9 4Gb 300 7.8 3.9 Rev. 1.01 DDR3L SDRAM 13.2 Refresh Parameters by Device Density [ Table 44 ] Refresh parameters by device density Parameter All Bank Refresh to active/refresh cmd time Average periodic refresh interval 8Gb 350 7.8 3.9 Units ns µs µs 1 NOTE NOTE : 1.
