1. A method of programming One-Time Programmable (OTP) memory, comprising: providing a plurality of OTP cells, at least one of the OTP cells including at least: an OTP element including at least one electrical fuse having a first terminal coupled to a first supply voltage line, the at least one electrical fuse having a fuse resistance, and a selector coupled to the OTP element with an enable signal coupled to a second supply voltage line; and one-time programming the at least one OTP cell into a different logic state by applying a plurality of voltage or current pulses to the at least one OTP cell via the first and the second supply voltage lines to turn on the selector and to thereby progressively change the fuse resistance.
