An error correction code block including dual-syndrome generators, which may process a plurality of successive code word without latency, is configured to calculate syndrome values of a corresponding even numbered codeword among the plurality of code words by using one of the dual-syndrome generators, and is configured to calculate syndrome values of a corresponding odd numbered codeword among the plurality of code words by using the other of the dual-syndrome generators.

Error correction code block having dual-syndrome generator, method thereof, and system having same

A memory controller and an operating method of the memory controller are provided. The operating method includes: performing error correction on data, including a plurality of chunks, in a unit of a chunk; determining if a coefficient of each term of which a degree is equal to or greater than a degree of a reference-degree term, in an error location polynomial for a last chunk among the plurality of chunks, is all zero; and controlling an output time of an error-corrected first chunk based on a result of the determining.

Method for operating memory controller and devices having the same

A decoder, a method of decoding and systems implementing the same are disclosed. In one example, the method includes calculating syndrome values from input codewords, generating an error location polynomial about the codewords using the syndrome values, determining an error count in the codewords using the error location polynomial, and adjusting power consumption of a circuit in response to the determined error count in the codewords. In one example, a frequency of a clock signal to be provided to a search circuit may be determined based on the error count, and the clock signal may be provided having the determined frequency to a search circuit, such as a Chien search circuit.
