Memory Module Specification
KVR400X72RC3A/256
256MB 32M x 72-Bit DDR400 CL3
Registered 184-Pin ECC DIMM
DESCRIPTION:
This document describes ValueRAM's 32M x 72-bit (256MB) DDR400 CL3 SDRAM
(Synchronous DRAM) Registered ECC memory module. The components on this module
include nine 32M x 8-bit (8M x 8-bit x 4 Bank) DDR4003 SDRAM in TSOP packages and
three 16-bit drivers in TSSOP 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)
Row Cycle Time (tRC)
5ns (min.) / 10ns (max.)
55ns (min.)
Refresh Row Cycle Time (tRFC) 70ns (min.)
Row Active Time (tRAS)
Single Power Supply of
Power (IDD0)
40ns (min.) / 70,000ns (max.)
+2.6V (+/- .1V)
4.125 W (operating)
94 V - 0
UL Rating
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 1.200" (30.48mm).
