    Abstract: A method of controlling repair of a volatile memory device, includes, performing a patrol read operation repeatedly to provide error position information of errors included in read data from a volatile memory device, generating accumulated error information by accumulating the error position information based on the patrol read operation performed repeatedly, determining error attribute based on the accumulated error information, the error attribute indicating correlation between the errors and a structure of the volatile memory device, and performing a runtime repair operation with respect to the volatile memory device based on the accumulated error information and the error attribute. The errors may be managed efficiently to prevent failure of the volatile memory device, and thus performance and lifetime of the volatile memory device and the storage device may be enhanced.

    Abstract: A semiconductor memory device includes a memory cell array, an error correction code (ECC) engine, an input/output (I/O) gating circuit connected between the memory cell array and the ECC engine, an error information register and a control logic circuit. The memory cell array includes a plurality of memory cell rows. The control logic circuit controls the ECC engine, the I/O gating circuit and the error information register based on a command and address. The I/O gating circuit provides the ECC engine with codewords which are read from the memory cell array through refresh operations on the plurality of memory cell rows. The ECC engine performs an ECC decoding on main data of the codewords based on parity bits of the codewords and provides error generation signals to the control logic circuit in response to detecting correctable errors with respect to a corresponding address resulting from performing the ECC decoding.
