PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor storage device which is improved in operational reliability.SOLUTION: A nonvolatile semiconductor storage device in one embodiment includes a memory cell array and a control circuit. A memory cell array, which includes a plurality of memory cells, stores initial setting data in each of the plurality of storage areas. The control circuit reads the initial setting data from the plurality of storage areas. When detecting an error in the initial setting data that is read from one of the plurality of storage areas, the control circuit reads the initial setting data from another storage area. |
