DATA SHEET
1GB Unbuffered DDR2 SDRAM DIMM
EBE11UD8AGFA (128M words
64 bits, 2 Ranks)
Description
The EBE11UD8AGFA is 128M words
64 bits, 2 ranks
DDR2 SDRAM unbuffered module, mounting 16 pieces
of 512M bits DDR2 SDRAM sealed in FBGA (
BGA
)
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 4 bits 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 FBGA (
BGA) on the module board.

Note: Do not push the components 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
=
1.8V
0.1V
Data rate: 667Mbps/533Mbps/400Mbps (max.)
SSTL_18 compatible I/O
Double-data-rate architecture: two data transfers per
clock cycle
Bi-directional, differential 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
and data mask referenced to both edges of DQS
Four internal banks for concurrent operation
(components)
Data mask (DM) for write data
Burst lengths: 4, 8
/CAS Latency (CL): 3, 4, 5
Auto precharge operation for each burst access
Auto refresh and self refresh modes
