摘要： When a voltage level detector detects that a supply voltage reaches a recovery voltage level that requires a recovery operation, a signal generator generates a recovery operation instructing signal for instructing the recovery operation. The recovery operation instructing signal is invalidated if a certain operation mode is executed and validated in other cases.

摘要： A semiconductor storage device includes a main memory cell array and a redundancy memory cell array. The redundancy memory cell array is set to selectively have a replacing area replacing a defective memory cell in the main memory cell array, and a non-replacing area other than the replacing area. Memory cells in the main memory cell array and the redundancy memory cell array are selected and driven by a memory selection circuit. A control section for controlling the memory selection circuit is set to assign main memory addresses to memory cells in the non-replacing area, and use these memory cells as an expansion area of the main memory cell array.
