Abstract:
According to one embodiment, a semiconductor memory device includes a memory cell, a first voltage generator and a second voltage generator. The memory cell is provided above a substrate. The first voltage generator is provided between the substrate and the memory cell. The first voltage generator is configured to generate a first voltage to be supplied to the memory cell. The second voltage generator is provided between the substrate and the memory cell. The second voltage generator is configured to generate the first voltage and have a circuit configuration equivalent to the first voltage generator.
