Memory Module Specification KVR133X72RC3L/256 256MB 32M x 72-Bit PC133 Registered CL3 Low Profile ECC 168-Pin DIMM DESCRIPTION: This document describes ValueRAM's 32M x 72-bit (256MB) CAS Latency 3 (CL3) Registered SDRAM (Synchronous DRAM) PC133 low profile memory 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) 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) 4.323 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 1.2" (30.48mm).
