Abstract

A CMOS-compatible high voltage multiplexer (HV MUX) for zero-additional-mask CMOS one time programmable (OTP) memory array mask is presented. The HV MUX uses standard CMOS with low input voltage and produce high output voltage beyond the V_DD allowed by the process for programming the OTP memory array. By limiting the instantaneous voltage between any two nodes, the HV MUX can tolerate the high voltages for programming without sacrificing reliability. Two configurations of CMOS OTP memory array using the HV MUX are presented and simulated to confirm the functionality of the design.
