MT46V32M16 – 8 Meg x 16 x 4 Banks
Features
• V
• V
• Bidirectional data strobe (DQS) transmitted/
• Internal, pipelined double-data-rate (DDR)
• Differential clock inputs (CK and CK#)
• Commands entered on each positive CK edge
• DQS edge-aligned with data for READs; center-
• DLL to align DQ and DQS transitions with CK
• Four internal banks for concurrent operation
• Data mask (DM) for masking write data
• 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 is supported
