Abstract :
Reducing the operating voltage is one of the most efficient ways to reduce the power dissipation of deep submicron ULSIs. A new bus architecture that reduces the operating power by using a bus signal swing of less than 1 V is proposed. This enables reduction of the bus swing to 1/3 that of the conventional architecture while maintaining a high speed and a low standby current. This architecture provides an efficient way to relieve the constraint of subthreshold leakage on V/sub CC/ scaling and to reduce the operating power of deep submicron ULSIs. Circuit configuration and performance are presented, together with experimental results.<>
