Abstract
A secure control circuit protects data stored in a memory is provided. A setting circuit provides a first activation signal and protection information. The protection information points to a confidential area of the memory. A processing circuit provides a second activation signal and access information. An arbiter determination circuit determines whether the access information points to the confidential area according to the protection information in response to the first activation signal being in a first level. In response to the second activation signal not being in a specific level and the access information points to the confidential area, the arbiter determination circuit directs an access circuit to access the confidential area. In response to the second activation signal being in the specific level and the access information points to the confidential area, the arbiter determination circuit directs the access circuit to stop accessing the confidential area.
