Memory Module Specification

KVR133X64SC3L/256

PC133 SDRAM 144-Pin CL3

SODIMM Memory Module

DESCRIPTION:

This document describes ValueRAM's CL3 32M x 64-bit (256MB) SDRAM (Synchronous
DRAM) PC133 Small Outline DIMM memory module. The components on this module include
sixteen 16M x 8-bit (4M x 8-bit x 4 Bank / PC133 components) 4K Refresh SDRAM inUBGA
packages. This 144-pin SODIMM uses gold contact fingers and requires +3.3V. The electrical
and mechanical specifications are as follows:

FEATURES:

CLK Cycle Time (tCC) min. = 7.5ns (CAS Latency = 3) / max. = 1000ns
Row Cycle Time (tRC) 65ns
CLK to Output (tSAC) max. = 5.4ns (CAS Latency = 3)
Single Power Supply of +3.3V (+/- .3V)
Power 3.168 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).
