FEATURES

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

? DLL circuitry for wide output data valid window and future

freguency 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 early write.

? Registered address, control and data input/output.

? DDR(Double Data Rate) Interface on read and write ports.

? Fixed 2-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 (x9, x18, x36) function.

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

? Simple depth expansion with no data contention.

? Programmable output impenance.

? JTAG 1149.1 compatible test access port.

? 165FBGA(11x15 ball aray FBGA) with body size of 15x17mm
