ABSTRACT:
A current memory cell comprises a first bipolar transistor providing a current source and coupled to the emitters of a second and a third bipolar transistor, the latter forming the storage elements of the memory cell. The memory cell is calibrated, to avoid mismatch between the second and third transistors, by adjustment of the current source via a parallel arrangement of a resistor and a field effect transistor in the emitter circuit of the first transistor.
