Abstract
The present invention provides a semiconductor storage device that requires no specialized circuit or the like for reading redundancy data from a redundancy region, and that is capable of freely changing the arrangement of the redundancy region in the memory array area. A semiconductor storage device of the present invention includes a memory array configured as shown below. The memory array includes a user region which is composed of given page units and where user data is stored, and a redundancy region which is composed of the same given page units and where redundancy data is stored. The area in the memory array can be used either as the user region or as the redundancy region.
