DESCRIPTION
This document describes ValueRAM’s 128M x 64-bit (1GB)
SPECIFICATIONS
Clock Cycle Time (tCK) CL=4 3.75ns (min.) / 8ns (max.)
DDR2-533 CL4 SDRAM (Synchronous DRAM) memory module.
The components on this module include eight 128M x 8-bit
DDR2-533 SDRAM in FBGA packages. This 240-pin DIMM
uses gold contact ngers and requires +1.8V. The electrical and
mechanical specications are as follows:
Note: The module dened in this data sheet is one of several congurations available under this part number. While all congurations are compatible, the DRAM
combination and/or the module height may vary from what is described here.
