Key Features
- 1.8V+0.1V/-0.1V Power Supply.
- DLL circuitry for wide output data valid window and future fre- quency scaling.
- I/O Supply Voltage 1.5V+0.1V/-0.1V for 1.5V I/O, 1.8V+0.1V/ -0.1V for 1.8V I/O.
- Separate independent read and write data ports with concurrent read and write operation
- HSTL I/O
- Full data coherency, providing most current data.
- Synchronous pipeline read with self timed late write.
- Registered address, control and data input/output.
- DDR (Double Data Rate) Interface on read and write ports.
- Fixed 4-bit burst for both read and write operation.
