The EBD51RC4AKFA is a 64M×72 bits, 1 rank Double Data Rate (DDR) SDRAM Module, mounting 18 pieces of DDR SDRAM sealed in TSOP package. It features high-speed data transfer, high-density mounting, and reliable data bus design.
HB52E328EM-A6B and HB52E329EM are 8-byte DIMM (Dual In-line Memory Module) produced by Elpida Memory, which are optimized main memory solutions for 8-byte processor applications.
This document is a preliminary data sheet for the 2G bits DDR2 SDRAM product. The product features a double-data-rate architecture, allowing for two data transfers per clock cycle. The high-speed data transfer is achieved through a 4-bit prefetch pipelined architecture. Bi-directional differential data strobe (DQS and /DQS) is used to transmit/receive data and capture data at the receiver. DQS is edge-aligned with data for READs and center-aligned with data for WRITEs. The product is available in two organizations: 64M words × 4 bits × 8 banks or 32M words × 8 bits × 8 banks. It supports multiple data rates, page sizes, burst lengths, and /CAS latency options.
