- DDR(Double Data Rate) Interface on read and write ports.
- Fixed 4-bit burst for both read and write operation.
- Clock-stop supports to reduce current.
- Two input clocks(K and K) for accurate DDR timing at clock rising edges only.
- Two input clocks for output data(C and C) to minimize clock-skew and flight-time mismatches.
- Two echo clocks (CQ and CQ) to enhance output data traceability.
- Single address bus.
- Byte write function.
- Simple depth expansion with...
