Abstract: An apparatus includes a memory device and a microcontroller device integrated with the memory device. The microcontroller device is adapted to be communicatively coupled to a processor device and is configured to manage access by the processor device to data stored on the memory device. Managing access by the processor device to the data stored on the memory device includes setting an access permission for controlled data stored by the memory device based on authorization data stored in the memory device. Managing access by the processor device further includes receiving, from the processor device, a request to access the controlled data. Managing access by the processor device further includes determining whether to initiate access to the controlled data by the processor device based on the access permission.
