Memory Module Specification

KVR266X72C2/512

512MB 64M x 72-Bit DDR266

CL2 ECC 184-Pin DIMM

DESCRIPTION:

This document describes ValueRAM's 64M x 72-bit (512MB) DDR266 CL2 SDRAM (Synchronous DRAM) ECC memory module. The components on this module include eighteen 32M x 8-bit DDR266 SDRAM in TSOP packages. This 184-pin DIMM uses gold contact fingers and requires +2.5V. The electrical and mechanical specifications are as follows:

FEATURES:

Clock Cycle Time (tCK) 7.5ns (min.) / 12ns (max.) Row Cycle Time (tRC) 65ns (min.) Refresh Row Cycle Time (tRFC) 75ns (min.) Row Active Time (tRAS) 45ns (min.) / 120,000ns (max.) Single Power Supply of +2.5V (+/- .25V) Power (IDD0) 3.262 W (operating) UL Rating 94 V - 0

Note: The module defined in this data sheet is one of several configurations available under this part number. While all configurations are compatible, the DRAM combination and/or the module height may vary from what is described here. However, in no configuration will the module height exceed 1.250" (31.75mm).
