Memory Module Specification KVR266X64C25/1G 1GB 128 x 64-Bit DDR266 CL2.5 184-Pin DIMM DESCRIPTION: This document describes ValueRAM's 128M x 64-bit 1GB (1024MB) DDR266 CL2.5 SDRAM (Synchronous DRAM) memory module. The components on this module include sixteen 64M x 8-bit DDR266 SDRAM in TSOP packages. This 184-pin DIMM uses gold contact fingers and requires +2.5V. The electrical and mechanical specifications are as follows: FEATURES: Clock Cycle Time (tCK) Row Cycle Time (tRC) Refresh Row Cycle Time (tRFC) Row Active Time (tRAS) Single Power Supply of Power UL Rating
7.5ns (min.) / 12ns (max.) 65ns (min.) 75ns (min.) 45ns (min.) / 120,000ns (max.) +2.5V (+/- .2V) 5.200 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 1.250" (31.75mm).
