Memory Module Specification
KVR133X72C3/256
256MB 32M x 72-Bit PC133
CL3 ECC 168-Pin DIMM Module
DESCRIPTION:
This document describes ValueRAM's 32M x 72-bit (256MB) CL3 PC133 SDRAM (Synchronous DRAM) ECC DIMM module. The components on this module include nine
32M x 8-bit (8M x 8-bit x 4 Bank) PC133 SDRAM in TSOP packages. This 168-pin DIMM
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 2.376 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 1.375" (34.92mm).
