Semiconductor memory device

摘要

According to one embodiment, there is provided a semiconductor memory device including a memory cell array, a storage unit, a selection unit, a startup processing unit, and an operation control unit. The memory cell array includes memory cells. The storage unit stores a plurality of operating parameters. The selection unit accesses the storage unit and selects a first operating parameter for operating the memory cells from among the plurality of operating parameters stored in the storage unit, based on a first instruction input. The startup processing unit performs a power startup and reads out the first operating parameter from the storage unit and sets the first operating parameter so as to be ready for use, based on a second instruction input. The operation control unit uses the first operating parameter set by the startup processing unit in order to operate the memory cells.
