Abstract
In a semiconductor memory device, a first plane includes a first memory cell array provided above a substrate in a first direction. A first power supply circuit is provided between the substrate and the first memory cell array, and a first sense amplifier is provided between the substrate and the first memory cell array. A second plane includes a second memory cell array provided above the substrate and a second power supply circuit provided between the substrate and the second memory cell array. A second sense amplifier is provided between the substrate and the second memory cell array. When viewed in the first direction, the first power supply circuit and the first sense amplifier overlap the first memory cell array, and the second power supply circuit and the second sense amplifier overlap the second memory cell array.
