DESCRIPTION
Kingston’s KHX8500D2K4/4G is a kit of four 128M x 64-bit 1GB (1024MB) DDR2-1066 CL5 SDRAM (Synchronous DRAM) memory modules, based on sixteen 64M x 8-bit DDR2 FBGA components per module. Total kit capacity is 4GB (4096MB). Each module kit 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 5-5-5-18 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: 5-5-5-18 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), single sided component
