Reading non-volatile multilevel memory cells

Image Number 6 for United States Patent #8130542.

Embodiments of the present disclosure provide methods, devices, modules, and systems for reading non-volatile multilevel memory cells. One method includes receiving a request to read data stored in a first cell of a first word line, performing a read operation on an adjacent cell of a second word line in response to the request, determining whether the first cell is in a disturbed condition based on the read operation. The method includes reading data stored in the first cell in response to the read request by applying a read reference voltage to the first word line and adjusting a sensing parameter if the first cell is in the disturbed condition.
