Memory Module Specification

DESCRIPTION:

This document describes ValueRAM's 128M x 64-bit 1GB (1024MB) DDR2-400 CL3

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

sixteen 64M x 8-bit (16M x 8-bit x 4 Bank) DDR2-400 SDRAM in FBGA packages. This

200-pin SODIMM uses gold contact fingers and requires +1.8V. The electrical and mechani-

cal 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) 75ns

Row Active Time (tRAS) 40ns (min.) / 70,000ns (max.)

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

Power 2.304 W (operating)

UL Rating 94 V - 0

Document No. VALUERAM0370-001.A00
