This document describes Kingston’s 256M x 64-bit 2GB (2048MB) DDR2-800 CL4 SDRAM (Synchronous DRAM) memory module, based on sixteen 128M x 8-bit DDR2 FBGA components per module. This module has been tested to run at DDR2 800MHz at low latency timing of 4-4-4-12 at 1.95V. The SPD is programmed to JEDEC standard latency 667Mhz timing of 5-5-5-15 at 1.8V. This 240-pin DIMM uses gold contact fingers and requires +1.8V. The electrical and mechanical specifications are as follows:
  • Power supply : Vdd: 1.8V ± 0.1V, Vddq: 1.8V ± 0.1V
  • Double-data-rate architecture; two data transfers per
    clock cycle
  • Bidirectional data strobe(DQS)
  • Differential clock inputs (CK and CK)
  • DLL aligns DQ and DQS transition with CK transition
  • Programmable Read latency 3, 4, 5 (clock)
  • Burst Length: 4, 8 (Interleave/nibble sequential)
  • Programmable Burst type (sequential & interleave)
  • Timing Reference: 667MHz 5-5-5-15 at +1.8V / 800MHz
    4-4-4-12 at +1.95V
  • Edge aligned data output, center aligned data input
  • Auto & Self refresh, 7.8us refresh interval (8K/64ms refresh)
  • Serial presence detect with EEPROM
  • High Performance Heat Spreader
  • PCB : Height 1.180” (30.00mm), double sided component
  • Clock Cycle Time (tCK) CL=5 3ns (min.) / 8ns (max.)
  • Row Cycle Time (tRC) 54ns (min.)
  • Refresh to Active/Refresh 127.5ns
  • Command Time (tRFC)
  • Row Active Time (tRAS) 39ns (min.) / 70,000ns (max.)
  • Single Power Supply of +1.8V (+/- .1V)
  • Power 2.592 W
  • UL Rating 94 V - 0
  • Operating Temperature 0° C to 55° C
  • Storage Temperature -55° C to +125° C
