Description

The EDD5108AD and the EDD5116AD are 512M bits Double Data Rate (DDR) SDRAM, organized as 16,777,216 words × 8 bits × 4 banks and 8,388,608 words × 16 bits × 4 banks, respectively.

Read and write operations are performed at the cross points of the CK and the /CK. This high-speed data transfer EDD5108AD and the EDD5116AD is realized by the 2 bits prefetch-pipelined architecture.  Data strobe (DQS) both for read and write are available for high speed and reliable data bus design. By setting extended mode register, the on-chip Delay Locked Loop (DLL) can be set enable or disable. They are packaged in standard 66-pin plastic TSOP(II).
