  • Semiconductor device having a programmable memory cell
    Patent number: 5471419
    Abstract: A semiconductor device having a programmable memory cell which includes a bipolar transistor of which a base region (13) can be provided with a base current through a control transistor (7, 8, 9, 10). The bipolar transistor has an emitter region (12) connected to a first supply line (151) and has a collector region (14) connected to a second supply line (152) through a load (16). A constant potential difference is maintained between the two supply lines (151, 152) during operation. The collector region (14) is laterally electrically insulated and provides a feedback to the control transistor in such a manner that, during operation within a certain voltage domain, a change in the voltage difference between the emitter region (12) and the collector region (14) leads to an opposite change in the conductivity through the control transistor.
