Abstract

Systems, apparatus, articles of manufacture, and methods are disclosed to enforce security through physical memory regions. An example apparatus includes memory including at least one region, a first integrated circuit (IC) coupled to the memory, and a second IC coupled to the memory. The example second IC is to, after successful attestation of at least one of first code or first data associated with a first region of the memory, adjust a first security level of the first region based on the at least one of the first code or the first data, and permit or deny an access request to the first region by the first IC based on (1) a type of the access request, (2) the first security level of the first region, and (3) a second security level of a second region in which second code is stored, the second code associated with the access request.
