Abstract
A method of correcting an error in a memory array in a DRAM during a read operation, wherein the memory array includes a data array and an ECC array, the method comprising: reading data from the memory array; when the data contains one or more erroneous data bits, correcting the erroneous data bits by an ECC decoding and correcting module in the DRAM; registering only corrected erroneous data bits and their positions in a register; controlling a plurality of write drivers in the DRAM by the register so as to write only the corrected erroneous data bits back to the memory array.
