Original Abstract Submitted

the present disclosure describes techniques and apparatuses that are directed to using memory protection data within a computing device. techniques include allocating regions of a memory for storing application data and protection data. techniques also include creating a bitmap having bit values corresponding to memory blocks within the allocated regions. the one or more bit values can be indicative of whether application data and/or protection data are present in a memory block. the techniques and apparatuses can enable memory protection, such as memory security (e.g., encryption) and memory safety (e.g., error correction code (ecc) usage), to be efficiently used while permitting discontiguous memory allocations and without substantial operating system modification.
