    摘要: A memory cell array has a plurality of memory cells formed of EEPROM cells arranged in a matrix form. Data in the memory cells is flash-erased, and after this, word lines other than a selected word line are set to a negative potential and erasing verification for detecting an insufficiently erased memory cell is effected. The flash-erasing and erasing verification are repeatedly effected until no insufficiently erased memory cell is detected. When no insufficiently erased memory cell is detected, word lines other than a selected word line are set to a negative potential and an overerased memory cell is detected. When an overerased memory cell is detected, weak program is effected for the cell by applying a voltage lower than the normal writing voltage to the cell.

    摘要: A semiconductor integrated circuit device includes fuse cells arranged at a fuse cell array, a fuse cell data program and erase circuit, a fuse cell data control circuit, and fuse data latch circuits. The fuse cells include erasable and programmable nonvolatile memory cells. The fuse cell data program and erase circuit programs fuse data to the memory cells and erases the fuse data from the memory cells. The fuse cell data control circuit controls read out timing of the fuse data stored in the memory cells based on a signal generated upon detection of power-on. The fuse data latch circuits latch the fuse data read out from the memory cells.

    摘要: A semiconductor integrated circuit device includes a nonvolatile memory cell, a source of the cell receiving a ground potential, and a gate of the cell receiving a first control signal; a transistor, a source of the transistor receiving a drain potential of the cell, and a gate of the transistor receiving a second control signal; and a controller. The controller receives a third control signal generated upon detection of power-on and outputs the first and second control signals. A potential of the first control signal changes from the ground potential to a potential different from the ground potential, which is maintained during a first period of time, and a potential of the second control signal changes from the ground potential to a potential different from the ground potential, which is maintained during a second period of time.
