    摘要: In one embodiment, the semiconductor device includes a memory array and a control architecture configured to control reading data from and writing data to the memory array. The control architecture is configured to receive data and a codeword location in the memory array, select one or more data units in the received data based on a data mask, read a codeword currently stored at the codeword location in the memory array, error correct the read codeword to generate a corrected read codeword, form a new codeword from the selected data units of the received data and data units in the corrected read codeword that do not correspond to the selected data units, and write the new codeword to the memory array.

    摘要: A semiconductor memory device includes a memory cell array, an input/output (I/O) gating circuit, an error decision circuit and an error check and correction (ECC) circuit. The I/O gating circuit reads test pattern data to provide test result data in a test mode and reads a codeword in a normal mode. The error decision circuit determines the correctability of errors in the test result data by a first unit, based on the test pattern data and the test result data and provides a first error kind signal indicating a first determination result, in the test mode. The ECC circuit decodes the codeword including main data and parity data generated based on the main data, determines correctability of errors in the codeword by a second unit and provides a second error kind signal indicating a second determination result, in the normal mode. The main data includes a plurality of unit data.
