Description
• Internal Double-Date-Rate architecture with twice accesses per clock cycle.
• Single 2.5V ±0.2V Power Supply
• 2.5V SSTL-2 compatible I/O
• Burst Length (B/L) of 2, 4, 8
• 2.5, 3 clock read latency
• Bi-directional, intermittent data strobe (DQS)
• All inputs except data and DM are sampled at the positive edge of the system clock.
• Data Mask (DM) for write data
• Sequential & Interleaved Burst type available
• Auto precharge option for each burst accesses
• DQS edge-aligned with data for Read cycles
• DQS center-aligned with data for Write cycles
• DLL aligns DQ & DQS transiti.
