Abstract
According to one embodiment, a semiconductor memory device includes a memory cell array having memory cells, word lines connected to the memory cell array, a generation circuit configured to generate voltages required for operations of the memory cell array, selection circuits connected to the word lines, respectively, each of the selection circuits being configured to select a voltage applied to a word line from the voltages, and a transfer unit configured to transfer items of control data for selecting the voltage to the selection circuits, respectively. The transfer unit includes transfer circuits which shift an enable signal in sequence. The transfer circuits include latch circuits which hold the items of control data based on the shifted enable signal, respectively.
