Memory Module Specification
KVR400D2N3/1G
1GB 128M x 64-Bit DDR2-400
DESCRIPTION:
This document describes ValueRAM's 128M x 64-bit (1GB) DDR2-400 CL3 SDRAM
(Synchronous DRAM) memory module. The components on this module include eight
128M x 8-bit DDR2-400 SDRAM in FBGA packages. This 240-pin DIMM uses gold contact
fingers and requires +1.8V. The electrical and mechanical specifications are as follows:
