ERROR CORRECTION METHOD AND APPARATUS: abstract simplified (18327374)

• This abstract for appeared for patent application number 18327374 Titled 'ERROR CORRECTION METHOD AND APPARATUS'

Simplified Explanation

The abstract describes methods and apparatus for error correction. It explains that a register controller detects errors in a memory and identifies the memory address where the error occurs. The controller then reads the raw data from that address, stores a preset first data in the same address, and reads a second data from the address. By comparing the first and second data, the controller determines the location of the first failure in the memory. It then retrieves the raw data stored in that location and performs error correction on it.

Original Abstract Submitted

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.
