The W632GG8KB is a 2G bits DDR3 SDRAM and speed involving -11, -12/12I and -15/15I

  • Features

    Power Supply: VDD, VDDQ = 1.5 V ± 0.075 V
    Double Data Rate architecture: two data transfers per clock cycle
    Eight internal banks for concurrent operation
    8 bit prefetch architecture
    CAS Latency: 6, 7, 8, 9, 10, 11 and 13
    Burst length 8 (BL8) and burst chop 4 (BC4) modes: fixed via mode register (MRS) or selectable On-The-Fly (OTF)
    Programmable read burst ordering: interleaved or nibble sequential
    Bi-directional, differential data strobes (DQS and DQS#) are transmitted / received with data
    Edge-aligned with read data and center-aligned with write data
    DLL aligns DQ and DQS transitions with clock
    Differential clock inputs (CK and CK#)
    Commands entered on each positive CK edge, data and data mask are referenced to both edges of a differential data strobe pair (double data rate)
    Posted CAS with programmable additive latency (AL = 0, CL - 1 and CL - 2) for improved command, address and data bus efficiency
    Read Latency = Additive Latency plus CAS Latency (RL = AL + CL)
    Auto-precharge operation for read and write bursts
    Refresh, Self-Refresh, Auto Self-refresh (ASR) and Partial array self refresh (PASR)
    Precharged Power Down and Active Power Down
    Data masks (DM) for write data
    Programmable CAS Write Latency (CWL) per operating frequency
    Write Latency WL = AL + CWL
    Multi purpose register (MPR) for readout a predefined system timing calibration bit sequence
    System level timing calibration support via write leveling and MPR read pattern
    ZQ Calibration for output driver and ODT using external reference resistor to ground
    Asynchronous RESET# pin for Power-up initialization sequence and reset function
    Programmable on-die termination (ODT) for data, data mask and differential strobe pairs
    Dynamic ODT mode for improved signal integrity and preselectable termination impedances during writes
    1K Byte page size
    Interface: SSTL_15
WBGA78 Ball (8x10.5mm2), RoHS compliant
