Abstract
Methods and systems are disclosed herein for detecting problems related to copyback programming. After the copyback data is read into the internal flash buffer, a part of the copyback data stored in the internal flash buffer (such as spare data) is analyzed to determine whether there are any errors in a part of the copyback data read. The analysis may be used by the flash memory in one or more ways related to the current copyback operation, subsequent copyback operations, subsequent treatment of the data in the current copyback operation, and subsequent treatment of the section in memory associated with the source page.
