Memory Module Specification KVR100X64C3/256 100MHz SDRAM 168-Pin PC100 Memory Module DESCRIPTION: This document describes ValueRAM's 32M x 64-bit (256MB), CAS Latency 3 (CL3) SDRAM (Synchronous DRAM) 100MHz memory module. The components on this module include sixteen 16M x 8-bit PC100 CL3 SDRAM components in TSOP packages. This 168pin 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. = 10ns (CAS Latency = 3) / max. = 1000ns 70ns max. = 6ns (CAS Latency = 3) +3.3V (+/- .3V) 4.658 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).
