Memory Module Specification
DESCRIPTION:
This document describes ValueRAM's 256M x 72-bit 2GB (2048MB) DDR2-400 CL3
SDRAM (Synchronous DRAM) ECC memory module. The components on this module
include eighteen 128M x 8-bit (32M x 8-bit x 4 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) 105ns
Row Active Time (tRAS) 40ns (min.) / 70,000ns (max.)
Single Power Supply of +1.8V (+/- .1V)
Power 2.615 W (operating)
UL Rating 94 V - 0
