EFFICIENT STORAGE OF MEMORY VERSION DATA

摘要

Systems and methods for efficient memory corruption detection in a processor. A processor detects a first data structure is to be allocated in a physical memory. The physical memory may be a DRAM with a spare bank of memory reserved for a hardware failover mechanism. Either the processor or an operating system (OS) determines a first version number corresponding to the first data structure. During initialization of the first data structure, the first version number may be stored in a first location in the spare bank. The processor receives from the OS a pointer holding the first version number. When the processor executes memory access operations targeting the first data structure, the processor compares the first version number with a third version number stored in a location in the physical memory indicated by the memory access address. The processor may set a trap in response to determining a mismatch.
