Abstract
During a garbage collection process for a non-volatile memory device of a storage device, an adaptive copy-back method selectively performs either an external or an internal copy-back operation in view of certain performance conditions for a storage device. The external copy-back operation is performed when a number of error-corrected bits per unit size of read data exceeds a given threshold value, and the internal copy-back operation is performed when the number of error-corrected bits does not exceed the threshold value.
