ABSTRACT:
A circuit for reading bipolar storage cells includes a storage element formed of two fed-back inverters, each of the inverters being formed of a multi-emitter transistor and a load element connected to a respective one of the multi-emitter transistors, two complementary bit-lines each being connected to one emitter of a respective one of the multi-emitter transistors, a first potential source, two bit-line current sources each being connected between the first potential source and a respective one of the complimentary bit-lines, a differential amplifier having two inputs, two read transistors each having a collector-emitter path connected between a respective one of the inputs of the differential amplifier and a respective one of the complimentary bit-lines, a second potential source, a read-current source connected to the second potential source, and two diode paths each connected between the read-current source and a respective one of the complimentary bit-lines.
