Memory Module Specification
DESCRIPTION:
ValueRAM's KVR400X64C3AK2/1G is a kit of two 64M x 64-bit (512MB) CL3 DDR400
SDRAM (Synchronous DRAM) memory modules. Total kit capacity is 1GB (1024MB). The
components on each module include sixteen 32M x 8-bit (8M x 8-bit x 4 Bank) DDR400
SDRAM in TSOP packages. Each 184-pin DIMM uses gold contact fingers and requires
+2.6V. The electrical and mechanical specifications are as follows:
