DATA SHEET
4GB Registered DDR2 SDRAM DIMM
EBE41RE4AAHA
(512M words
×
72 bits, 2 Ranks)
Description
The EBE41RE4AAHA is a 512M words
×
72 bits, 2
ranks DDR2 SDRAM Module, mounting 36 pieces of
1G bits DDR2 SDRAM with sFBGA stacking
technology. 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. Data strobe (DQS and /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. This module provides high
density mounting without utilizing surface mount
technology. Decoupling capacitors are mounted
beside each SDRAM on the module board.
Note: Do not push the cover or drop the modules in
order to avoid mechanical defects, which may
result in electrical defects.
Features
240-pin socket type dual in line memory module
(DIMM)
PCB height: 30.0mm
Lead pitch: 1.0mm
Lead-free (RoHS compliant)
Power supply: VDD, VDDQ
=
1.8V
±
0.1V
Data rate: 533Mbps/400Mbps (max.)
SSTL_18 compatible I/O
Double-data-rate architecture: two data transfers per
clock cycle
Bi-directional, data strobe (DQS and /DQS) is
transmitted /received with data, to be used in
capturing data at the receiver
DQS is edge aligned with data for READs; center
aligned with data for WRITEs
Differential clock inputs (CK and /CK)
DLL aligns DQ and DQS transitions with CK
transitions
Commands entered on each positive CK edge; data
referenced to both edges of DQS
Eight internal banks for concurrent operation
