KHX6400D2B1K2/4G
4GB (2GB 256M x 64-Bit x 2 pcs.)
PC2-6400 CL5 240-Pin DIMM Kit
DESCRIPTION:
Kingston's KHX6400D2B1K2/4G is a kit of two 256M x 64-bit 2GB (2048MB) DDR2-800 CL5 SDRAM (Synchronous DRAM) memory modules, based on sixteen 128M x 8-bit DDR2 FBGA components. Total kit capacity is 4GB (4096MB). The SPDs are 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: 800MHz 5-5-5-15 at +1.8V
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
