SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

Logic arrays which apply outputs to logic circuitry are made to exhibit improved noise characteristics which, in turn, improve performance of the logic circuitry. The improvement is achieved by providing a distributed ground throughout the logic array to provide local closed loop paths for discharge currents generated in the array. In this manner, discharge currents are not allowed to flow in ground or power BUSES and so do not affect the driven logic circuitry.
