Memory Module Specification
DESCRIPTION:
This document describes ValueRAM's 64M x 72-bit (512MB) DDR400 CL3 SDRAM (Syn-
chronous DRAM) "single rank" Registered ECC memory module. The components on this
module include eighteen 64M x 4-bit (16M x 4-Bit x 4 bank) DDR400 SDRAM in FBGA
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.) / 70,000ns (max.)
Single Power Supply of +2.6V (+/- .1V)
Power 5.850 W operating
UL Rating 94 V - 0
