Abstract

This paper proposes printed organic one-time programmable read-only memory (PROM). The organic PROM cell consists of a capacitor and an organic p-type metal-oxide semiconductor (PMOS) transistor. Initially, all organic PROM cells with unbroken capacitors store "0." Some organic PROM cells are programmed to "1" by electrically breaking each capacitor with a high voltage. After the capacitor breaking, the current flowing through the PROM cell significantly increases. The memory data is read out by sensing the current in the PROM cell. 16-bit organic PROM cell arrays are fabricated with the printed organic PMOS transistor and capacitor process. The organic PROM cells are programmed with -50 V, and they are read out with -20 V. The area of the 16-bit organic PROM array is 70.6 $mm^2$.
