• 2.5V I/O (SSTL_2 compatible)

• Commands entered on each positive CK edge

• DQS edge-aligned with data for READs; center-

• Internal, pipelined double data rate (DDR)

• Bidirectional data strobe (DQS) transmitted/

• Differential clock inputs CK and CK#

• Four internal device banks for concurrent operation

• Programmable burst lengths: 2, 4, or 8

• Auto precharge option

• Auto refresh and self refresh modes

• 7.8125µs maximum average periodic refresh

• Serial presence detect (SPD) with EEPROM

• Programmable READ CAS latency

• Gold edge contacts

• Dual rank
