PRELIMINARY DATA SHEET

256M bits DDR2 SDRAM

for HYPER DIMM

EDE2508AASE-DF, -BE, -AE (32M words × 8 bits)

EDE2516AASE-DF, -BE, -AE (16M words × 16 bits)

Description

Features

The EDE2508AA is a 256M bits DDR2 SDRAM

• 1.8V power supply

organized as 8,388,608 words × 8 bits × 4 banks.

• Double-data-rate architecture: two data transfers per

clock cycle

It is packaged in 64-ball FBGA package.

• Bi-directional, differential data strobe (DQS and

/DQS) is transmitted/received with data, to be used in

capturing data at the receiver

The EDE2516AA is a 256M bits DDR2 SDRAM

organized as 4,194,304 words × 16 bits × 4 banks.

It is packaged in 84-ball FBGA package.

• 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

• 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

• 7.8µs average periodic refresh interval

• 1.8V (SSTL_18 compatible) I/O

• Posted CAS by programmable additive latency for

better command and data bus efficiency

• Off-Chip-Driver Impedance Adjustment and On-Die-

Termination for better signal quality

• Programmable RDQS, /RDQS output for making × 8

organization compatible to × 4 organization

• /DQS, (/RDQS) can be disabled for single-ended

Data Strobe operation.

• FBGA package with lead free solder (Sn-Ag-Cu)
