DESCRIPTION:

Kingston's KHX8500D2K2/4G is a kit of two 256M x 64-bit 2GB (2048MB) DDR2-1066 CL5

SDRAM (Synchronous DRAM) memory modules, based on sixteen 128M x 8-bit DDR2 FBGA

components per module. Total kit capacity is 4GB (4096MB). Each module pair has been tested to

run at DDR2- 1066MHz at a latency timing of 5-5-5-15 at 2.2V. The SPD is programmed to JEDEC

standard latency 800Mhz timing of 5-5-5-15 at 1.8V. Each 240-pin DIMM uses gold contact fingers

and requires +1.8V. The electrical and mechanical specifications are as follows:

FEATURES:

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 5 (clock)

Burst Length: 4, 8 (Interleave/nibble sequential)

Programmable Burst type (sequential & interleave)

Timing Reference: 5-5-5-15 at +1.8V / 5-5-5-15 at +2.2V

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

PERFORMANCE:

Clock Cycle Time (tCK) CL=5 2.5ns (min.) / 8ns (max.)

Row Cycle Time (tRC) 51.5ns (min.)
