NON-VOLATILE MEMORY DEVICES AND SYSTEMS INCLUDING MULTI-LEVEL CELLS USING MODIFIED READ VOLTAGES AND METHODS OF OPERATING THE SAME

摘要

Methods of operating a multi-level non-volatile memory device can include accessing data, stored in the device, which is associated with read voltages and modifying the read voltages applied to a plurality of multi-level non-volatile memory cells to discriminate between states stored by the cells in response to a read operation to the multi-level non-volatile memory device. Related devices and systems are also disclosed.
