DESCRIPTION:
This document describes Kingston's 32M x 64-bit (256MB) DDR434 SDRAM (Synchronous
DRAM) CL2 memory module. The components on this module include eight 32M x 8-bit (8M x 8-
bit x 4 Bank / 217MHz, 4.6ns) DDR434 SDRAM in TSOP packages. This 184-pin DIMM uses gold
contact fingers and requires +2.6V. The electrical and mechanical specifications are as follows:
