Abstract:
A semiconductor memory device includes a plurality of pass transistors disposed along a first direction over a substrate, and configured to transfer operating voltages to a memory cell array; and a plurality of global lines formed in a first wire layer over the pass transistors, extending in a second direction intersecting with the first direction, and configured to transfer the operating voltages to the corresponding pass transistors respectively. The global lines are disposed in first direction pitches of some pass transistors among the pass transistors.
