Techniques for Error Correction of Encoded Data

摘要

Examples are disclosed for techniques for error correction of encoded data. In some examples, error correction code (ECC) information for the ECC encoded data may be received that indicates the ECC encoded data includes one or more errors. A determination may be made as to whether the ECC encoded data includes a single error, two errors or more than two errors. If the ECC encoded data includes a single error, an error location of the error may be identified. If the ECC encoded data includes two errors, first and second error locations may be identified. If the ECC encoded data includes more than two errors, separate error locations may be identified for the more than two errors. The single error, the two errors or the more than two errors may be corrected and the ECC encoded data may then be decoded. Other examples are described and claimed.

主权项

1. An apparatus, comprising:
circuitry for a memory system; a single error component for execution by the circuitry to receive error correction code (ECC) information for ECC encoded data, and identify a location of a single error in the ECC encoded data or when more than a single error generate a first indication of multiple errors; a double error component for execution by the circuitry to receive the ECC information, and identify locations for two errors in the ECC encoded data or when more than two errors generate a second indication of multiple errors; a multiple error component for execution by the circuitry to receive the ECC information and separately identify locations for each of the multiple errors; and a corrector component for execution by the circuitry to receive the identified locations for the one or more errors and correct the one or more errors in the ECC encoded data.
