Memory Module Specification

DESCRIPTION:

This document describes ValueRAM's 64M x 72-bit (512MB) DDR2-667 CL5 SDRAM

(Synchronous DRAM) ECC memory module. The components on this module include

nine 64M x 8-bit (16M x 8-bit x 4 Bank) DDR2-667 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=5 3ns (min.) / 8ns (max.)

Row Cycle Time (tRC) 54ns (min.)

Refresh to Active/Refresh Command Time (tRFC) 105ns

Row Active Time (tRAS) 39ns (min.) / 70,000ns (max.)

Single Power Supply of +1.8V (+/- .1V)

Power 1.701 W (operating)

UL Rating 94 V - 0

Document No. VALUERAM0431-001.A00
