    Abstract: Example error correction methods and apparatus are described. In one example method, a register controller detects an error existing in a memory, and after detecting an uncorrected error (UCE), obtains a memory address in which the UCE occurs. The register controller reads raw data from a location indicated by the memory address, stores preset first data in the location indicated by the memory address, and reads second data from the location after storing the first data in the location. The register controller compares the first data with the second data to determine a first failure location in the location, determines raw data stored in the first failure location from the raw data in the location, and performs error correction on the raw data stored in the first failure location.
