Abstract :
A 9-ns 16-Mb CMOS SRAM has been developed using a 0.35-μm CMOS process, The current-mode fully nonequalized data path has been realized in a CMOS SRAM for the first time by using a stabilized feedback current-sense amplifier (SFCA) that provides a small input resistance and an offset compensation effect. To reduce the test time, a bit-line wired-OR parallel test circuit has been implemented
