Systematic mitigation of memory errors

A computing device for managing memory, the computing device comprising:

• a system memory;
• and
• a processor, wherein the system memory and the processor respectively store and execute at least a portion of an Operating System (OS) for the computing device, wherein the OS allocates regions of the system memory for use by the OS and by one or more applications, and wherein the OS including a memory manager that performs operations comprising:
• while the OS is executing, encountering an error condition associated with execution of a software component, the error condition indicative of a likely failure within a first memory region of the system memory;
• the memory manager receiving an indication of the error condition associated with execution of the software component;
• in response to the received indication of the error condition, detecting a failure within the first memory region;
• adding an indication that the first region has been determined to be faulty to a stored list of faulty memory regions;
• and
• using the stored list of faulty memory regions to allocate at least a second memory region of the system memory for use by one or more software components, wherein the second memory region is not indicated as faulty according to the stored list of faulty memory regions.

A computing device for managing memory, the computing device comprising:

• a memory;
• and
• a processor, wherein the system memory and the processor respectively store and execute instructions that:
• run an Operating System (OS) using at least a portion of the memory;
• identify at least a first region of the memory to be tested;
• perform a diagnostic test of at least the first region, wherein the diagnostic test comprises:
• a scan of at least the first region;
• and
• a determination that the first region is faulty;
• maintain stored information about faulty memory regions;
• in response to a determination that the first region is faulty, add an indication that the first region is faulty to the stored information about faulty memory regions;
• and
• allocate one or more regions of the memory to one or more software components running on the computing device, the allocation comprising checking the stored information about faulty memory regions and excluding memory regions indicated as faulty according to the stored information.

At least one computer-readable storage memory having computer-executable instructions stored therein, that when executed by a processor of a computer system, perform operations comprising:

• running an Operating System (OS), wherein the OS uses at least a portion of the memory;
• identifying at least a first region, of a plurality of regions of the memory, to be tested;
• performing a diagnostic test of at least the first region, wherein the diagnostic test comprises:
• scanning at least the first region;
• and
• determining that the first region is faulty;
• maintaining stored information about faulty memory regions;
• in response to determining that the first region is faulty, adding an indication that the first region is faulty to the stored information about faulty memory regions;
• and
• allocating one or more regions of the memory to one or more software components running on the computer system, the allocating comprising checking the stored information about faulty memory regions and allocating the one or more regions of the memory from memory regions that are not indicated as faulty according to the stored information.
