Abstract: Techniques and mechanisms to facilitate data error detection by a memory controller. In an embodiment, the memory controller calculates, for each of a plurality of data blocks, a respective result based on a first metadata value and data of that data block, where the first metadata value describes a characteristic which is common to each of the plurality of data blocks. With each such calculated result, the memory controller further performs a respective error detection analysis, wherein such analysis is based on a retrieved error correction code for a corresponding one of the plurality of data blocks. In another embodiment, a single version of the metadata value is stored by the memory controller, where the single version of the metadata value is made available to facilitate error detection for any of the plurality of data blocks.

Abstract: Examples are disclosed for techniques associated with error correction for encoded data. In some examples, error correction code (ECC) information for the ECC encoded data is received that indicates the ECC encoded data includes one or more errors. A determination is made as to whether the ECC encoded data includes either a single error or more than one error. If the ECC encoded data includes a single error, an error location of the error is identified. If the ECC encoded data includes more than one error, separate error locations are identified for the more than one error. The single error or the more than one error is corrected and the ECC encoded data is then be decoded.
