Memory Module Specification

KVR400D2S8R3/1G

1GB 128M x 72-Bit DDR2-400

CL3 Registered 240-Pin ECC DIMM

DESCRIPTION:

This document describes Kingston's 128M x 72-bit 1GB (1024MB) DDR2-400 CL3 SDRAM
(Synchronous DRAM) "single rank" registered ECC memory module. The components on this
module include nine 128M x 8-bit (16M x 8-bit x 8 Bank) DDR2-400 SDRAM in FBGA
packages. This 240-pin DIMM uses gold contact fingers and requires +1.8V. The electrical and
mechanical specifications are as follows:

FEATURES:

Clock Cycle Time (tCK) CL=3 5ns (min.) / 8ns (max.)
Row Cycle Time (tRC) 55ns (min.)
Refresh to Active/Refresh Command Time (tRFC) 127.5ns
Row Active Time (tRAS) 40ns (min.) / 70,000ns (max.)
Single Power Supply of +1.8V (+/- .1V)
Power 2.335 W (operating)
UL Rating 94 V - 0

Note: The module defined in this data sheet is one of several configurations available under this part number. While
all configurations are compatible, the DRAM combination and/or the module height may vary from what is described
here. However, in no configuration will the module height exceed 1.250" (31.75mm).
