A 1.2 GHz high-speed 256-bit shift register LSI

The authors have developed a high-speed 256-bit shift register LSI intended for use in gigabit-rate signal storage applications in GaAs MESFET DCFL/SBFL (direct-coupled FET logic/superbuffer FET logic) circuits. This shift register has serial data input and serial data output composition, suitable for line memory usage. To attain both high-speed and low power characteristics, the authors used a serial-input-data to parallel-internal-data and parallel-internal-data to serial-output-data conversion system. The maximum clock rate under which this device can operate is 1.2 GHz. It has a low (1.2-W) power consumption from a single 2-V power supply.<
