Abstract

PURPOSE:To enhance the current concentration of a junction destructive programmable memory cell by dividing a collector region into plural regions, providing collector electrodes in the respective regions, providing base and emitter regions at both sides of the electrode, and flowing writing current only in predetermined direction of the respective cells. CONSTITUTION:Collector regions 19, 20 are divided into plural regions, and collector electrodes 21, 22 are provided at every collector regions 19, 20. Then, base regions 5-8 and emitter regions 9-12 are provided at both sides of the collector electrodes 21, 22. Thus, writing currents from the electrode layers 13-16 flow only in predetermined direction (an arrow in the drawing) of the respective cells.
