DESCRIPTION:
This document describes Kingston's 128M x 64-bit 1GB (1024MB) DDR2-800 CL5 SDRAM
(Synchronous DRAM) memory module, based on sixteen 64M x 8-bit DDR2 FBGA components.
This module has been tested to run at DDR2 800MHz at low latency timing of 5-5-5-15 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 specifica-
tions 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 +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
