ABSTRACT:
A semiconductor memory device for a flash EEPROM includes MOS transistors, each used as a fuse element for storing function control data and having a stacked gate structure in which a floating gate and a control gate are stacked on each other, and a sequence control circuit for pre-charging the drain of a MOS transistor as a fuse element upon reception of a predetermined control signal, reading out data from the MOS transistor after the pre-charge operation, and latching the readout data.
