Abstract
A universal memory device is presented that provides adaptability to existing hardware and software environments. The memory can “mimic” existing memory technology combining the advantages of integrating all memory capacity into one single technology and still providing the implicit protections and access characteristics known from the different existing memory technologies. The memory device comprises a memory having low-latency, rewritable, non-volatile memory cells, a profile storage unit connected with the memory and comprising access information allocated to a set of request information elements (request profile), such that the access information indicates whether an access request to said memory, the access request having the request profile, is to be allowed or rejected, and an access control unit communicating with the profile storage unit and the memory, and adapted to allow or reject an incoming access request in dependence on the access information allocated to the request profile of the access request.
