ABSTRACT:
An electrically alterable memory cell is described which has a capacitive imbalance for causing the memory cell to assume either of its two stable states, and which uses a capacitor as a non-volatile storage element for retaining the information stored in the memory cell during power down operation. The capacitor has an alterable capacitance-voltage curve which is employed to identify the information in the bistable multivibrator just prior to loss of power. When power is returned, the capacitor causes the bistable multivibrator to assume that stable state in which it was operating at the time power was lost.
