A first decoder circuit is given a first drive voltage to provide a control signal to the redundant memory cell. A dummy memory cell has a threshold voltage corresponding to the redundant memory cell. A second decoder circuit is given a second drive voltage corresponding to the first drive voltage to provide a control signal to the dummy memory cell. A comparator circuit compares data to be read out of the dummy memory cell with data actually read out of the dummy memory cell.

The first row decoder applies a positive voltage to the word lines in a write operation and in an erase operation. The second row decoder applies a negative voltage to the word lines in a write operation and in an erase operation. The first isolating transistor switches between the first row decoder and the word line. The second isolating transistor switches between the second row decoder and the word line.

    摘要: A semiconductor memory device includes memory cells, a memory cell array, word lines, a row decoder, and first and second MOS transistors. The memory cell has a floating gate and a control gate. The word line connects commonly the control gates. The row decoder decodes a row address signal. The first MOS transistor transfers a first voltage to the word line unselected by the row decoder. The first MOS transistor has a drain connected to the word line and a source to which the first voltage is applied. A back gate bias for the first MOS transistor is controlled independently of a potential at the source of the first MOS transistor. The second MOS transistor transfers a second voltage to the word line selected by the row decoder. The second MOS transistor has a drain connected to the word line and a source to which the second potential is applied.
