Abstract

The present invention provides a circuitry including a processor, a one-time programmable memory and an access control circuit. The one-time programmable memory includes a first area and a first access control data, wherein the first access control data is used to indicate whether the first area can be written or read by the processor. When the processor writes or reads the first area through the access control circuit, the access control circuit determines whether to write or read the first area according to the first access control data, and the access control circuit determines what kind of data for sending back to the processor.
