Features

DD
Q = +2.5V ±0.2V
• Bidirectional data strobe (DQS) transmitted/received
with data, i.e., source-synchronous data capture (x16 has
two – one per byte)
• Internal, pipelined double data rate (DDR) architecture;
two data accesses per clock cycle
• Differential clock inputs (CK and CK#)
• Commands entered on each positive CK edge
• DQS edge-aligned with data for READs; center-aligned
with data for WRITEs
• DLL to align DQ and DQS transitions with CK
• Four internal banks for concurrent operation
• Data mask (DM) for masking write data (x16 has two – one
per byte)
• Programmable burst lengths: 2, 4, or 8
• Auto Refresh and Self Refresh Modes
• Longer-lead TSOP for improved reliability (OCPL)
• 2.5V I/O (SSTL_2 compatible)
• Concurrent auto precharge option supported
