PRELIMINARY DATA SHEET

1GB Registered DDR SDRAM DIMM

EBD10RD4ABFA

(128M words

72 bits, 1 Rank)

Description

The EBD10RD4ABFA is 128M words

72 bits, 1 rank

Double Data Rate (DDR) SDRAM registered module,

mounting 18 pieces of 512M bits DDR SDRAM sealed

in TSOP 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 2-bit

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

set enable or disable. This module provides high

density mounting without utilizing surface mount

technology.

Decoupling capacitors are mounted

beside each TSOP on the module board.
