Memory Module Specification
KVR266X64SC25/1G
1GB 128M x 64-Bit DDR266
DESCRIPTION:
This document describes ValueRAM's 128M x 64-bit (1GB) CL2.5 SDRAM (Synchronous
DRAM) DDR266 memory module. The components on this module include sixteen
64M x 8-bit (16M x 8-bit x 4 Bank) DDR266 SDRAM sealed in TCP packages. This 200pin DIMM uses gold contact fingers and requires +2.5V. The electrical and mechanical
specifications are as follows:
FEATURES:
Clock Cycle Time (tCK) 7.5ns (min.) / 12ns (max.)
Row Cycle Time (tRC) 65ns (min.)
Refresh Row Cycle Time (tRFC) 75ns (min.)
Row Active Time (tRAS) 45ns (min.) / 120,000ns (max.)
Single Power Supply of +2.5V (+/- .25V)
Operating (IDD0) 3.900 W
UL Rating 94 V - 0
CL2.5 200-Pin SODIMM
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).
