Memory Module Specification
KVR400X64SC3A/256
256MB 32M x 64-Bit DDR400
CL3 200-Pin SODIMM
DESCRIPTION:
This document describes ValueRAM's 32M x 64-bit (256MB) DDR400 CL3 SDRAM
(Synchronous DRAM) memory module. The components on this module include eight
16M x 16-bit (4M x 16-bit x 4 Bank ) DDR400 SDRAM in TSOP packages. This 200-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
Operating (IDD0)
UL Rating
40ns (min.) / 70,000ns (max.)
+2.6V (+/- .1V)
2.525 W
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).
