Hardware fault detection method for internal memory, apparatus, and internal memory controller

A device, comprising:

• an internal memory comprising a target location;
• and
• an internal memory controller coupled to the internal memory and configured to:
• perform error correction on data at the target location to obtain first corrected data;
• write the first corrected data into the target location;
• read first data from the target location after the internal memory controller writes the first corrected data into the target location;
• record, when no error exists in the first data, the target location;
• and
• report an error message when an error exists in the first data, wherein the error message indicates that a hardware fault has occurred at the target location.

A computer program product comprising instructions that are stored on a non-transitory computer-readable medium and that, when executed by an internal memory controller, cause a device to:

• perform error correction on data at a target location in an internal memory to obtain first corrected data;
• write the first corrected data into the target location;
• read first data from the target location after the internal memory controller writes the first corrected data into the target location;
• record, when no error exists in the first data, the target location;
• and
• report an error message when an error exists in the first data, wherein the error message indicates that a hardware fault has occurred at the target location.
