Abstract
A secure memory device for secure data storage and related method are provided. The device may include an accessible data storage area configured to store data, a start location register that points to a start of the accessible data storage area, and a size-related register that allows a size of the accessible data storage area to be determined. A secret area comprises a device secret that is a value unique to the device, and that is not accessible from external to the device, and is accessible under at least one predefined conditions internal to the device, an access control element configured to prevent external access to the secret data. A generator generates a derived secret based on the storage data and the secret data that is usable to authenticate the storage data. The device may also include a memory bus over which the derived secret is communicated.
