EBE21RD4AEFA-6 Datasheet 2GB Registered DDR2 SDRAM DIMM

Manufacturer: Elpida Memory

Datasheet Details

The EBE21RD4AEFA is a 256M words × 72 bits, 2 ranks DDR2 SDRAM Module, mounting 36 pieces of 512M bits DDR2 SDRAM sealed in FBGA package.

Read and write operations are performed at the cross points of the CK and the /CK.

This high-speed data transfer is realized by the 4bits prefetch-pipelined architecture.
