Abstract
A slow programming audit is performed on one or more memory blocks and/or associated word lines of one or more memory dies. The slow programming audit is used to determine whether identified or known weak word lines of one or more memory dies are causing performance issues. If it is determined that the weak word lines are causing data read, data write and/or data retention issues, the weak word lines of the one or more memory dies are marked for slow programming in subsequent programming operations.
