    • PURPOSE: A method of operating a memory controller and devices including the memory controller improve the performance of a read operation by controlling the output timing of an error corrected first chunk. CONSTITUTION: Error correction is performed from first to (N-1)^th chunks among object data including N (N is integer) chunks (S10). It is determined that coefficients of an order term equal to or greater than a reference order term of an error location polynomial expression are all 0 for the N^th chunk among the N chunks (S40). The output timing of the error corrected first chunk is controlled based on the determined result. [Reference numerals] (AA) Start a read action; (BB) End the read action; (S10) Correct errors from a first chunk to a (N-1)^th chunk in a chunk-by-chunk manner; (S20) Store a N^th chunk in a memory device; (S30) Calculate syndrom values for the N^th chunk; (S40) Are the coefficients of the N^th chunk equal to or larger than a reference order term of an error location polynomial expression all 0 ?; (S51) Output the chunks in which errors are corrected in order with the first chunk being the start, while the N^th chunk is corrected; (S52) Calculate the values of the error location polynomial expression; (S53) Output the N^th chunk with its errors corrected; (S54) Correct the N^th chunk's errors; (S56) Output the chunks in which errors are corrected in order with the first chunk being the start and the N^th chunk being the ending point

    • A method for compensating data skew in a memory device and a memory controller adopting the same are disclosed. The method for compensating data skew comprises the steps of measuring at least one factor value affecting the data skew of a memory system; and adjusting a delay amount of a data strobe signal based on the measured factor value, wherein the factor value includes at least one of a level value and a temperature value of an internal voltage used by the memory system. [Reference numerals] (AA) Start; (BB) End; (S110) Measuring at least one factor value affecting the data skew; (S120) Adjusting a delay amount of a data strobe signal based on the measured factor value
