Abstract
A non-volatile device and method of operating the device including changing a read reference level for reading a group of memory cells as a function of changes in a threshold voltage distribution of a different group of memory cells. The changing step may include determining a history read reference level of a history cell associated with a group of memory cells of a non-volatile memory cell array and comparing sensed logical state distributions with stored logical state distributions.
