    摘要: For a verify operation using potential Vbi', the data of a memory cell (M1 through M16) is preliminarily read by using potential Vai+1 and the state of the memory cell is stored in a latch circuit. Then, a verify/read operation is conducted by using potential Vbi'. If the state of the cell is higher than Ai+1, the outcome of the verify/read operation is forcibly brought down to a low level. Thus, only two latch circuits (LAT(A), LAT(B)) are required for storing an n-bit data, including one for storing the data to be written and one for preliminarily reading if the state of the cell is higher than Ai+1 or not and storing the outcome of the preliminary reading.

    摘要: A redundancy memory cell array (12A, 12B) is arranged at an end of a main memory cell array (11A, 11B) in the column direction. Common bit lines and common column lines are arranged on the main memory cell array (11A, 11B) and the redundancy memory cell array (12A, 12B). A disconnection circuit (13A, 13B) is arranged between the main memory cell array (11A, 11B) and the redundancy memory cell array (12A, 12B) for connecting or disconnecting bit lines or column lines. A column selection switch (15A, 15B) is arranged at an end of the redundancy memory cell array (12A, 12B). A redundancy circuit (14) disconnects bit lines or column lines by means of a disconnection circuit (13A, 13B) when an address signal specifies a defective address.
