Detecting special handling metadata using address verification

Abstract:

Exemplary methods, apparatuses, and systems include receiving a read request directed to an addressable unit of memory. The read request includes an address for the addressable unit and the addressable unit includes a metadata portion. A mismatch between one or more bits of the address in the read request and a corresponding one or more bits of an address verification value in the metadata portion of the addressable unit is detected. A position of each of the one or more bits that did not match is determined to be an indication of special handling for the addressable unit of memory. In response to the indication of special handling, special handling metadata for the addressable unit of memory is read and the read request is processed according to the special handling metadata.
