PRELIMINARY DATA SHEET
256M bits DDR SDRAM
EDD2508AKTA-5 (32M words
× 8 bits, DDR400)
Description
The EDD2508AKTA-5 is a 256M bits DDR SDRAM
organized as 8,388,608 words
× 8 bits × 4 banks.
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 register, the on-chip
Delay Locked Loop (DLL) can be set enable or disable.
It is packaged in 66-pin plastic TSOP (II).
Features
• Power supply: VDDQ = 2.6V ± 0.1V
: VDD = 2.6V
± 0.1V
• Data rate: 400Mbps (max.)
• 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
• 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
 7.8µs maximum average periodic refresh interval
• 2 variations of refresh
 Auto refresh
 Self refresh
