Features
• VDD/VDDQ = 1.70–1.95V
• Bidirectional data strobe per byte of data (DQS)
• 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
• Four internal banks for concurrent operation
• Data masks (DM) for masking write data—one mask
per byte
• Programmable burst lengths: 2, 4, or 8
• Concurrent auto precharge option supported
• Auto refresh and self refresh modes
• 1.8V LVCMOS compatible inputs
• On-chip temperature sensor to control self refresh
rate
• Partial-array self refresh (PASR)
• Deep power-down (DPD)
• Selectable output drive (DS)
• Clock stop capability
• 64ms refresh period
