Systems and methods to provide write termination for one time programmable memory cells

Abstract:

A One Time Programmable (OTP) memory, includes: a first driver coupled to a reference cell by a first bit line; a second driver coupled to an OTP cell by a second bit line; and a comparator having a first input coupled to the first bit line and the reference cell, a second input coupled to the second bit line and the OTP cell, and an output coupled to a logic circuit configured to control the first driver and the second driver.
