Memory Module Specification

DESCRIPTION:

This document describes Kingston's 128M x 72-bit (1GB) DDR2-400 CL3 SDRAM (Syn-

chronous DRAM) dual rank registered ECC memory module. The components on this

module include eighteen 64M x 8-bit (16M 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 2.997 W (operating)

UL Rating 94 V - 0
