128MB Registered DDR SDRAM DIMM

EBD12RB8ALFB (16M words × 72 bits, 1 Bank)

Description

Features

The EBD12RB8ALFB is a 16M × 72 × 1 bank Double

Data Rate (DDR) SDRAM Module, mounted 9 pieces

of 128M bits DDR SDRAM (EDD1208ALTA) sealed in

TSOP package, 1 piece of PLL clock driver, 2 pieces of

EEPROM) for Presence Detect (PD). Read and write

operations are performed at the cross points of the

CLK and the /CLK. This high-speed data transfer is

realized by the 2bits 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 register, the on-chip Delay Locked

Loop (DLL) can be set enable or disable. An outline of

the products is 184-pin socket type package (dual lead

out). Therefore, it makes high density mounting

possible without surface mount technology. It provides

• 184-pin socket type dual in line memory module

(DIMM)

Outline: 133.35mm (Length) × 30.48mm (Height) ×

4.00mm (Thickness)

Lead pitch: 1.27mm

• 2.5V power supply (VDD/VDDQ)

• SSTL-2 interface for all inputs and outputs

• Clock frequency: 133MHz/100MHz (max.)

• Data inputs and outputs are synchronized with DQS

• 4 banks can operate simultaneously and

independently (Component)

• Burst read/write operation

• Programmable burst length: 2, 4, 8

Burst read stop capability

• Programmable burst sequence

Sequential

common data inputs and outputs.

Decoupling

capacitors are mounted beside each TSOP on the

module board.

Interleave

• Start addressing capability

Even and Odd

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

• 4096 refresh cycles: 15.6µs (4096/64ms)

• 2 variations of refresh

Auto refresh

Self refresh
