SYSTEM AND METHOD FOR READING MEMORY CELLS

Abstract:

The present disclosure provides a method, a circuit, and a system for reading memory cells. The method comprises: applying a first voltage with a first polarity to a plurality of the memory cells; applying a second voltage with a second polarity to one or more of said plurality of the memory cells; applying at least a third voltage with the first polarity to one or more of said plurality of the memory cells; detecting electrical responses of memory cells to the first voltage, the second voltage, and the third voltage; and determining a logic state of respective memory cells based on the electrical responses of the memory cells to the first voltage, the second voltage, and the third voltage.
