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).

Data rate: 333Mbps/266Mbps (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): 2, 2.5
Programmable output driver strength: normal/weak
Refresh cycles: 4096 refresh cycles/64ms
