Memory Module Specification KVR133X64C3Q/256 256MB 32M x 64-Bit PC133 CL3 168-Pin DIMM Module DESCRIPTION: This document describes ValueRAM's 32M x 64-bit (256MB) PC133 CL3 SDRAM (Synchronous DRAM) DIMM module. The components on this module include sixteen 16M x 8-bit (4M 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) Row Cycle Time (tRC) CLK to Output (tSAC) Single Power Supply of Power UL Rating
min. = 7.5ns (CAS Latency = 3) / max. = 1000ns 65ns max. = 5.4ns (CAS Latency = 3) +3.3V (+/- .3V) 3.168 W (operating) 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).
