Abstract
Memory verification using processing-in-memory is described. In accordance with the described techniques, memory testing logic is loaded into a processing-in-memory component. The processing-in-memory component executes the memory testing logic to test a memory. An indication is output of a detected fault in the memory based on testing the memory.
Claims20
A system comprising:
- a memory of a memory module, the memory including memory testing logic;
- and
- an in-memory processor disposed in the memory module, the in-memory processor configured to receive the memory testing logic from the memory, execute the memory testing logic in the in-memory processor to test the memory, and output an indication of a detected fault based on testing the memory.
A method comprising:
- loading memory testing logic, from a memory of a memory module, into an in-memory processor disposed in the memory module;
- executing, by the in-memory processor, the memory testing logic to test the memory;
- and
- outputting an indication of a detected fault in the memory based on testing the memory.
1 more element
A method comprising:
- accessing, by an in-memory processor disposed in a memory module, one or more portions of a memory of the memory module to test the memory, the one or more portions of the memory accessed according to a memory access pattern described by memory testing logic stored in the memory;
- and
- outputting, by the in-memory processor, an indication of whether the one or more portions of the memory are faulty or not faulty for receipt by an application in the memory, the application configured to initiate a response based on the indication, the indication based on comparing values written to the one or more portions of the memory with values read from the one or more portions of the memory.
