MEMORY DEVICES AND METHODS HAVING ADAPTABLE READ THRESHOLD LEVELS

A method can include determining at least one use characteristic for the memory cells comprising a solid electrolyte, the use characteristic corresponding to a number of times the memory cells have been programmed to at least one impedance level; and adjusting a read threshold level for the memory c...

Zusammenfassung:A method can include determining at least one use characteristic for the memory cells comprising a solid electrolyte, the use characteristic corresponding to a number of times the memory cells have been programmed to at least one impedance level; and adjusting a read threshold level for the memory cells based on at least the use characteristic, the read threshold level determining data values stored in the memory cells in a read operation.
