FEATURES

? 1.8V+0.1V/-0.1V Power Supply.

? DLL circuitry for wide output data valid window and future frequency 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.

? 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 (x18, x36) function.

? Separate read/write control pin(R and W)

? Simple depth expansion with no data contention.

? Programmable output impedance.
