Anti-fuse memory array embedded in 14nm FinFET CMOS with novel selector-less bit-cell featuring self-rectifying characteristics

Abstract

A novel anti-fuse memory array is presented in this paper featuring one-capacitor (1C) per bit-cell design and fully compatible with 14nm FinFET CMOS technology. The rectifying I-V characteristics of the metal-insulator-semiconductor (MIS) structure after programming prevents the sneak current in the cross-point array, therefore no need for select transistor in each cell. Thus enables the smallest reported bit-cell with area measuring 0.036 μm2.
