  • Allocation technique for memory diagnostics
    Patent number: 9691503
    Abstract: An apparatus for allocating computer memory for memory diagnostics is disclosed. The apparatus may include a processor and memory that stores code executable by the processor, and may include code that identifies an unreserved amount of memory in a computer system, code that requests a portion of the memory based on the unreserved amount of memory, and code that determines whether an allocated portion of the memory comprises non-contiguous memory addresses. In some embodiments, the apparatus includes code that locks the allocated portion of the memory in response to the allocated portion consisting solely of contiguous memory addresses, and code that performs a memory diagnostic test on the allocated portion of the memory.

  • Advanced memory test diagnostics
    Patent number: 9443613
    Abstract: For performing advanced memory test diagnostics, an apparatus, method, and computer program product are disclosed. The apparatus may include a processor, a memory that stores code executable by the processor, an address space module that identifies an address space having a plurality of blocks of memory addresses, a memory diagnostic module that performs, at least three times, a memory test procedure using a block pattern, wherein a first block pattern is used the first time, a second block pattern is used the second time, and a third block pattern is used the third time, and a memory fault module that determines the presence of a memory fault based on results of the memory test procedures.
