Description
The EDD2516AKTA-5 is a 256M bits DDR SDRAM
organized as 4,194,304 words
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.
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.
It is packaged in 66-pin plastic TSOP (II).
Features
Document No. E0638E20 (Ver. 2.0)
Date Published September 2005 (K) Japan
Printed in Japan
URL: http://www.elpida.com
Power supply: VDD, VDDQ = 2.6V
Data rate: 400Mbps (max.)
Double Data Rate architecture; two data transfers per
clock cycle
Bi-directional data strobe (DQS) is transmitted
/received with data for capturing data at the receiver
Data inputs, outputs, and DM are synchronized with
DQS
4 internal banks for concurrent operation
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
Data mask (DM) for write data
Auto precharge option for each burst access
SSTL_2 compatible I/O
Programmable burst length (BL): 2, 4, 8
Programmable /CAS latency (CL): 3
Programmable output driver strength: normal/weak
Refresh cycles: 8192 refresh cycles/64ms
2 variations of refresh
TSOP (II) package with lead free solder (Sn-Bi)
7.8 s maximum average periodic refresh interval
Auto refresh
Self refresh
RoHS compliant
