Abstract

A one time programmable memory circuit includes a one time programmable memory array. A write circuit outputs data to the one time programmable memory array. A power up write controller outputs the data and a write enable signal to the write circuit. A read circuit outputs data from the one time programmable memory array upon a read enable signal received from a read controller. An address decoder communicates with the power up write controller and the read controller, for providing an address to the one time programmable memory array.
