Memory Module Specification
DESCRIPTION:
ValueRAM's KVR533D2N4K2/2G is a kit of two 128M x 64-bit (1GB) DDR2-533 CL4
SDRAM (Synchronous DRAM) memory modules. Total kit capacity it 2GB. The compo-
nents on each module include sixteen 64M x 8-bit (16M x 8-bit x 4 Bank) DDR2-533
SDRAM in FBGA packages. Each 240-pin DIMM uses gold contact fingers and requires
+1.8V. The electrical and mechanical specifications are as follows:
