PRELIMINARY DATA SHEET

1GB Unbuffered DDR SDRAM DIMM

EBD11ED8ABFB (128M words × 72 bits, 2 Banks)

Description

Features

The EBD11ED8ABFB is 128M words × 72 bits, 2

• 184-pin socket type dual in line memory module

(DIMM)

banks Double Data Rate (DDR) SDRAM unbuffered

module, mounted 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

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

set enable or disable. This module provides high

density mounting without utilizing surface mount

PCB height: 31.75mm

Lead pitch: 1.27mm

• 2.5V power supply

• Data rate: 333Mbps/266Mbps (max.)

• 2.5 V (SSTL_2 compatible) I/O

• Double Data Rate architecture; two data transfers per

clock cycle

• Bi-directional, data strobe (DQS) is transmitted

/received with data, to be used in capturing data at

the receiver

technology.

Decoupling capacitors are mounted

beside each TSOP on the module board.

• Data inputs and outputs are synchronized with DQS

• 4 internal banks for concurrent operation

(Component)

• 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

• Auto precharge option for each burst access

• Programmable burst length: 2, 4, 8

• Programmable /CAS latency (CL): 2, 2.5

• Refresh cycles: (8192 refresh cycles /64ms)

7.8µs maximum average periodic refresh interval

• 2 variations of refresh

Auto refresh

Self refresh
