CLEARING POISON STATUS ON READ ACCESSES TO VOLATILE MEMORY REGIONS ALLOCATED IN NON-VOLATILE MEMORY
摘要
Systems and methods may provide for detecting that a read operation is directed to a memory region while the memory region is in a poisoned state and clearing the poisoned state if volatile data stored in the memory region does not correspond to a known data pattern. Additionally, the memory region may be maintained in the poisoned state if the volatile data stored in the memory region corresponds to the known data pattern. In one example, an error may be detected, wherein the error is associated with a write operation directed to the memory region. In such a case, the poisoned state may be set for the volatile data in response to the error and the known data pattern may be written to the memory region.
