Patent abstract

Technologies disclosed herein provide one example of a system that includes processor circuitry to be communicatively coupled to a memory circuitry. The processor circuitry is to receive a memory access request corresponding to an application for access to an address range in a memory allocation of the memory circuitry and to locate a metadata region within the memory allocation. The processor circuitry is also to, in response to a determination that the address range includes at least a portion of the metadata region, obtain first metadata stored in the metadata region, use the first metadata to determine an alternate memory address in a relocation region, and read, at the alternate memory address, displaced data from the portion of the metadata region included in the address range of the memory allocation. The address range includes one or more bytes of an expected allocation region of the memory allocation.
