US Patent 11929110 Memory circuit and method of operating same

A memory circuit includes a global control circuit, a first local control circuit, and a first set of word line post-decoder circuits coupled to a first set of memory cells that is configured to store a first set of data. The global control circuit is configured to generate a first and second set of global pre-decoder signals, and a first set of local address signals. The first local control circuit includes a first set of repeater circuits and a first clock pre-decoder circuit. The first set of repeater circuits is configured to generate a first and second set of local pre-decoder signals in response to the corresponding first and second set of global pre-decoder signals. The first clock pre-decoder circuit is configured to generate a first and second set of clock signals in response to the first set of local address signals and the first clock signal.
