A semiconductor memory device includes a main memory includes a nonvolatile memory, and a buffer which stores input/output data of the nonvolatile memory, a buffer unit of the main memory, the buffer unit includes a volatile memory, a self-test interface includes a data input/output pin, and a controller which controls the main memory and the buffer unit. The controller at least stores data in the buffer from the self-test interface via the data input/output pin.
