MEMORY FAULT PROCESSING SYSTEM, MEMORY FAULT PROCESSING METHOD, AND MEMORY FAULT PROCESSING PROGRAM

摘要

PPROBLEM TO BE SOLVED: To determine whether to continue or stop a process using a memory region according to the use of the process when the correctable defect of the memory occurs. PSOLUTION: To an entry registered in a TLB, "a defect frequency" and "a defect threshold " are added. The defect frequency holds the frequency of the correctable defect occurring in a corresponding physical address space. The defect threshold holds the maximum number of correctable defects permitted by the corresponding process. Also, a defect frequency monitoring mechanism connected to the TLB is provided with a function for comparing the defect frequency with the defect threshold, and when the defect frequency exceeds the defect threshold, issuing a signal to stop the process.
