Abstract: A hardware fault detection method includes, after performing error correction on data at a target location in an internal memory and writing corrected data into the target location, the internal memory controller reads first data from the target location. When determining that an error exists in the first data, the internal memory controller reports an error message, where the error message indicates that a hardware fault occurs at the target location. After finding that an error occurs in the data at the target location, the internal memory controller performs the error correction, write-back, and re-reading on the data, to further determine a type of the error occurring at the target location.
