ABSTRACT:
A integrity control system uses the address bits to enable protection of data stored in a system memory. An address bus that determines the location of data to be stored or retrieved from system memory has a plurality of address lines. A subset of the address lines enables the protection mechanism to generate an integrity control value representative of the data and determine where the integrity check value is stored in a secure memory.
