4GB – 2x256Mx72 DDR2 SDRAM RDIMM, w/PLL
DESCRIPTION
The WV3HG2256M72AER is a 2x256Mx72 Double Data
Rate DDR2 SDRAM high density module based on 1Gb
DDR2 SDRAM components. This memory module consists
of eighteen stacks of 256Mx4 bit with 8 banks DDR2
Synchronous DRAMs in FBGA packages, two - 14 bit
registered buffers in BGA packages mounted on a 240-pin
DIMM FR4 substrate.
