Abstract

The present disclosure provides a memory device comprising a memory cell array and a peripheral circuit coupled to the memory cell array. The memory cell array includes a plurality of memory planes; the peripheral circuit includes a plurality of selected voltage selection circuits corresponding to the plurality of memory planes; a plurality of global word line voltage selection circuits respectively corresponding to each memory plane, and a plurality of local word line voltage selection circuits respectively corresponding to each memory plane. The plurality of selected voltage selection circuits are configured to select a voltage from a plurality of selected voltages to output to the global word line voltage selection circuits; the global word line voltage selection circuits are configured to select a voltage from unselected voltages and the voltage output from the plurality of selected voltage selection circuits to output to the local word line voltage selection circuits.
