Kingston Technology 256MB 168PIN DIMM SDRAM KVR100X72C2L/256 Data Sheet

This document describes ValueRAM's 32M x 72-bit (256MB), CAS Latency 2 (CL2)
SDRAM (Synchronous DRAM) PC100 ECC memory module. The components on this
module include eighteen 16M x 8-bit (4M x 4-Bit x 4 bank) low profile PC100 CL2 SDRAM
components in TSOP packages. This 168-pin DIMM uses gold contact fingers and requires
+3.3V. The electrical and mechanical specifications are as follows:

CLK Cycle Time (t

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 1.2" (30.48mm).
