    摘要: The antifuse is brought into an electrically conducted state by setting the voltage Vpgm to a high voltage after activating the signal SA and setting the node N1 once to an L-level. By inversion of the latch, the voltage of the node N1 will be the power source voltage Vcc to bring the transistor into a non-conducted state, whereby the electric current flowing through the antifuse is cut off. A semiconductor device can be provided which includes an antifuse program circuit capable of cutting the electric current off after blowing, so as to prevent decrease in the blowing voltage.

    摘要: Normal memory cells and dummy cells are arranged continuously in a memory array. In a data read operation, first and second data lines are connected to the selected memory cell and the dummy cell, respectively, and are supplied with operation currents of a differential amplifier. An offset corresponding to a voltage difference between first and second offset control voltages applied from voltage generating circuits are provided between passing currents of the first and second data lines, and a reference current passing through the dummy cell is set to a level intermediate between two kinds of levels corresponding to storage data of a data read current passing through the selected memory cell.
