According to one embodiment, a semiconductor memory device includes a memory including a memory cell array, and an input/output pin configured to transfer data, a command, and an address from an external to the memory. The memory includes a termination circuit provided between the input/output pin and the memory cell array, and configured to supply a first voltage having a first amplitude in a first transfer mode and supply a second voltage having a second amplitude in a second transfer mode, a first intermediate value of the first amplitude being different from a second intermediate value of the second amplitude.
