SYSTEM FOR HANDLING ERRATIC WORD LINES FOR NON-VOLATILE MEMORY

摘要

A non-volatile storage system identifies a word line with an open neighbor word line and determines whether data stored in non-volatile memory cells connected to the identified word line has an error condition. If the data does have an error condition, then an attempt is made to fix the data and the open neighbor word line is checked for errors. If the open neighbor word line has errors, then memory cells connected to the open neighbor word line are programmed with pseudo data.

1. An apparatus, comprising:
non-volatile memory cells; and one or more control circuits in communication with the memory cells, the one or more control circuits configured to identify a word line with an open neighbor word line and determine whether data stored in non-volatile memory cells connected to the identified word line has an error condition, the one or more control circuits configured to cause an attempt to fix the data if the data has an error condition, the one or more control circuits configured to cause non-volatile memory cells connected to the open neighbor word line to be programmed with pseudo data.
