Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An adaptive copy-back method comprising: determining whether a performance reduction condition has occurred due to a number of operations allocated simultaneously to a buffer memory of a non-volatile memory device, the buffer memory external of the non-volatile memory device; reading data from a source page of the non-volatile memory device and storing the data in a page buffer within the non-volatile memory device; performing error correction on the dat…
