ONE-TRANSISTOR (1T) ONE-TIME PROGRAMMABLE (OTP) ANTI-FUSE BITCELL WITH REDUCED THRESHOLD VOLTAGE

Abstract:

A one-transistor (1T) one-time programmable (OTP) anti-fuse bitcell is provided. The 1T OTP anti-fuse bitcell includes a gate, a diffusion region including at least two sub-regions, and a gate oxide region located between the gate and the diffusion region, the gate oxide region including a thin gate oxide region and a thick gate oxide region.
