摘要： A fuse device and a program transistor are connected in series with each other. A flip-flop turns ON, in response to a start signal, the program transistor to start program of the fuse device. A 2-input NAND circuit outputs an end signal at a time point where change in a resistance value of the fuse device is increased to reach a predetermined level while monitoring change in the resistance value of the fuse device through change in a voltage at a junction point of the fuse device and the program transistor. The flip-flop turns OFF, in response to the end signal, the program transistor to automatically terminate the program of the fuse device. Thus, the resistance value of the fuse device is increased to the predetermined level in a minimum program time.

摘要： Selection signals output from a decoder are selectively set at High according to the states (blown or not blown) or fuses in bit cells in a cell group specifying circuit. Then, one of transistor gates is turned ON so that a data bit cell group in/from which data is written and read out is selected. Accordingly, stored data can be rewritten multiple times by sequentially blowing the fuses in the cell group specifying circuit.

摘要： In a normal operation, an output of a differential amplifier for amplifying a difference between first and second bit cells is output as readout data. In a test mode, when a first control signal is set to be “H”, the output of the differential amplifier is fixed to be “H” and thus an output of the first bit cell is read out through gates.
