Abstract
A decoder circuit to decode an address for accessing a memory cell in a memory array includes address latch circuitry, inverter circuitry, and first address pre-decode circuitry. The address latch circuitry receives an address signal and generates address holding signals during a setup period. The address latch circuitry latches the address holding signals during an address hold period following the setup period. The inverter circuitry receives the address signal and generates a complementary address signal. The first address pre-decode circuitry decodes the address signal and the address holding signals during the setup period to generate a first pre-decode address signal at an output of the first address pre-decode circuitry. In addition, the first address pre-decode circuitry decodes the address holding signals during the address hold period to maintain the first pre-decode address signal at the output of the first address pre-decode circuitry.
