    Abstract: A semiconductor memory device includes a memory cell array, an error correction code (ECC) engine, a scrubbing control circuit and a control logic circuit. The memory cell array includes memory cell rows, and each of the memory cell rows including volatile memory cells. The scrubbing control circuit generates scrubbing addresses for performing a normal scrubbing operation on the memory cell rows with a first period based on refresh row addresses for refreshing the memory cell rows. The control logic circuit controls the ECC engine the scrubbing control circuit to distribute a scrubbing operation on weak codewords dynamically within the refresh operation such that a dynamic allocated scrubbing (DAS) operation is performed with a second period smaller than the first period. An error bit is detected in each of the weak codewords during the normal scrubbing operation or normal read operation on at least one of the memory cell rows.

    Abstract: A semiconductor memory device includes a memory cell array, an error correction code (ECC) circuit, a fault address register, a scrubbing control circuit and a control logic circuit. The memory cell array includes memory cell rows. The scrubbing control circuit generates scrubbing addresses based on refresh operations performed on the memory cell array. The control logic circuit controls the ECC circuit such that the ECC circuit performs an error detection operation on a plurality of sub-pages in a first memory cell row to count a number of error occurrences, and determines whether to correct a codeword in which an error is detected based on the number of error occurrences. An uncorrected or corrected codeword is written back , and a row address of the first memory cell row may be stored in the fault address register as a row fault address based on the number of error occurrences.
