Mobile Low-Power DDR SDRAM

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

? 4 internal banks for concurrent operation

? Data masks (DM) for masking write data; one mask per byte

? Programmable burst lengths (BL): 2, 4, 8, or 16

? Concurrent auto precharge option is supported

? Auto refresh and self refresh modes

? 1.8V LVCMOS-compatible inputs

? Temperature-compensated self refresh (TCSR)

? Partial-array self refresh (PASR)

? Deep power-down (DPD)

? Status read register (SRR)

? Selectable output drive strength (DS)

? Clock stop capability

? 64ms refresh, 32ms for automotive temperature
