2Mx36-bit, 4Mx18-bit DDRII CIO b4 SRAM
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
.
Pipelined, double-data rate operation.
Common data input/output bus.
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 function.
Simple depth expansion with no data contention.
Programmable output impedance.
JTAG 1149.1 compatible test access port.
165FBGA(11x15 ball array FBGA) with body size of 15x17mm
& Lead Free
