PRELIMINARY DATA SHEET

4GB Registered DDR3 SDRAM DIMM

EBJ41RE4BAFA (512M words

72 bits, 2 Ranks)

Specifications

•

Density: 4GB

•

Organization



512M words

72 bits, 2 ranks

•

Mounting 36 pieces of 1G bits DDR3 SDRAM sealed

in FBGA

•

Package: 240-pin socket type dual in line memory

module (DIMM)



PCB height: 30.5mm (max.)



Lead pitch: 1.0mm



Lead-free (RoHS compliant)

•

Power supply: VDD

1.5V

0.075V

•

Data rate: 1333Mbps/1066Mbps/800Mbps (max.)

•

Eight internal banks for concurrent operation

(components)

•

Interface: SSTL_15

•

Burst lengths (BL): 8 and 4 with Burst Chop (BC)

•

/CAS Latency (CL): 5, 6, 7, 8, 9

•

/CAS write latency (CWL): 5, 6, 7

•

Precharge: auto precharge option for each burst

access

•

Refresh: auto-refresh, self-refresh

•

Refresh cycles



Average refresh period

7.8µs at 0°C

≤

≤ +85°C

3.9µs at

+85°C <

≤ +95°C

•

Operating case temperature range



TC = 0°C to +95°C

Features

•

Double-data-rate architecture; two data transfers per

clock cycle

•

The high-speed data transfer is realized by the 8 bits

prefetch pipelined architecture

•

Bi-directional differential data strobe (DQS and /DQS)

is transmitted/received with data for 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

•

Posted /CAS by programmable additive latency for

better command and data bus efficiency

•

On-Die-Termination (ODT) for better signal quality



Synchronous ODT



Dynamic ODT



Asynchronous ODT

•

Multi Purpose Register (MPR) for temperature read

out

•

ZQ calibration for DQ drive and ODT

•

Programmable Partial Array Self-Refresh (PASR)

•

/RESET pin for Power-up sequence and reset

function

•

SRT range:



Normal/extended



Auto/manual self-refresh

•

Programmable Output driver impedance control

•

1 piece of registering clock driver and 1 piece of

serial EEPROM (256 bytes EEPROM) for Presence

Detect (PD)

•

Class B temperature sensor functionality with

EEPROM
