  • Patent number: 12159677
    Abstract: A memory device includes a memory cell array, a voltage generation circuit generating one or more voltages supplied to the memory cell array, an input/output circuit receiving an address indicating a region in the memory cell array, and a control circuit controlling operations of the memory cell array. The control circuit supplies a non-selection voltage of the voltages before a ready/busy signal changes from a ready state to a busy state.
