    • PROBLEM TO BE SOLVED: To provide a non-volatile semiconductor storage device capable of fast accessing when reading/writing while avoiding the program in a selected cell or the data in the cell which is not selected at erasing from disturbed. SOLUTION: The non-volatile semiconductor storage device comprises a memory cell 100 containing first and second MONOS memory cells, and a plurality of memory cell array regions. A control drive part comprises a plurality of control gate drivers. A plurality of selection switching elements 9 are provided at the common connection point between a plurality of main bit lines MBLs and a plurality of sub bit lines SBLs. The sub bit line SBL comprises a protruding part 140 at one end part. The protruding part 140 has a wide region which is wider than the sub bit line SBL in the region where the memory cells 100 are provided.

    • PROBLEM TO BE SOLVED: To obtain a method and a device for efficiently achieving redundancy of a virtual grounded flash memory. SOLUTION: Floating gate field-effect transistors are arranged in columns and rows to form an array, and a floating gate field-effect transistor is prepared, where at least the same number of floating gate field-effect transistors as the number of columns of the above array are connected to a row line for redundancy. When a defect is generated in the row line, the thresholds of all floating gate field-effect transistors of at least one row being connected to the defective row line are set to a higher state, and at the same time are connected to the same number of redundant row lines as the number of floating gate field-effect transistors with the high threshold.
