DESCRIPTION
Kingston's KHX6400S2LLK2/4G is a kit of two 256M x 64-bit
(2GB) CL5 low latency SDRAM (Synchronous DRAM) 2Rx8
memory modules. Each module is based on sixteen 128M x 8-
bit DDR2 FBGA components. Total kit capacity is 4GB. The
SPDs are programmed to JEDEC low latency timing of 5-5-5-18
at 1.8V. Each 200-pin SODIMM uses gold contact fingers and
requires +1.8V. The electrical and mechanical specifications
are as follows:
