    摘要: A method, implemented by at least an error correction code (ECC) decoder and a controller, estimates and corrects errors in memory cells. The method includes identifying a first candidate group of memory cells having an error-generation possibility using a first method for error estimation; identifying a second candidate group of memory cells having an error-generation possibility using a second method for error estimation; and correcting errors in at least one cell commonly included in the first and second candidate groups.

    摘要: A data processing system includes an error checking and correction (ECC) encoding circuit, an integrated circuit memory and a code rate control circuit. The ECC encoding circuit is configured to selectively apply a plurality of unique ECC code rates to write data received by the data processing system during an operation to convert the write data into encoded data, in response to a code rate selection signal. The integrated circuit memory includes a plurality of storage regions therein. These storage regions are configured to receive respective portions of the encoded data from the ECC encoding circuit. The code rate control circuit is configured to generate the code rate selection signal. This code rate selection signal has a value that specifies the corresponding ECC code rate to be applied to respective portions of the write data.
