Abstract
A technique includes accessing error information generated in response to memory errors of a memory device. The error information generated in response to the memory errors of the memory device may then be determined as indicative of a row hammer error for the memory device.
Claims15
A method comprising:
- accessing, via a computing device, error information generated in response to memory errors of a memory device, wherein the error information includes hard errors and soft errors;
- and
- determining, via the computing device, whether the error information is indicative of a row hammer error.
A system, comprising:
- a memory device;
- and
- a memory controller coupled to the memory device, wherein the memory controller is to sample an error status register associated with the memory device to generate a data base of error information;
- and
- an error monitor to determine whether the error information is indicative of a row hammer error.
2 more elements
An article comprises a non-transitory storage medium to store instructions readable by a processor-based system which when executed by the processor-based system cause the processor-based system to:
- analyze a database of errors associated with a memory device;
- and
- determine that at least one of the errors associated with the memory device is a row hammer error.
