Memory Module Specification

KVR400X64C25/512

512MB 64M x 64-Bit DDR400

CL2.5 184-Pin DIMM

DESCRIPTION:

This document describes ValueRAM's 64M x 64-bit (512MB) CL2.5 DDR400 SDRAM
(Synchronous DRAM) memory module. The components on this module include sixteen
32M x 8-bit (8M x 8-bit x 4 Bank) DDR400 SDRAM in TSOP packages. This 184-pin DIMM
uses gold contact fingers and requires +2.6V. The electrical and mechanical specifications
are as follows:

FEATURES:

Clock Cycle Time (tCK) 5ns (min.) / 10ns (max.)
Row Cycle Time (tRC) 55ns (min.)
Refresh Row Cycle Time (tRFC) 70ns (min.)
Row Active Time (tRAS) 40ns (min.) / 100,000ns (max.)
Single Power Supply of +2.6V (+/- .1V)
Power (IDD0) 3.100 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).
