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.
Claims10
A one time programmable memory circuit comprising:
- a one time programmable memory;
- a write circuit providing data to the one time programmable memory;
- a power up write controller providing the data and a write enable signal to the write circuit;
- a read circuit outputting data from the one time programmable memory upon a read enable signal from a read controller;
- and
- an address decoder providing an address to the one time programmable memory for reading to and writing from the one time programmable memory.
A one time programmable memory circuit comprising:
- a one time programmable memory;
- a power up write controller providing data and a write enable signal to the one time programmable memory;
- a read circuit providing data from the one time programmable memory;
- and
- an address decoder providing an address to the one time programmable memory when the address is not a secure data address.
