ABSTRACT:
A data storage device consisting of at least two series connected resonant tunneling diodes (RTD1, RTD2) with capacitors (C1 ,C2) coupled thereacross. By coupling a time varying voltage V(t) across the series connected diodes, one the diodes can be selectively switched from a state below its peak current to a stable point above its peak current. The diode which switches state is controlled by the slope of the time varying voltage V(t). Cells consisting of at least two or more resonant tunneling diodes may be connected in series and can store up to 2.sup.N binary states where N is the number of resonant tunneling diodes in the cell.
