Latest Patents

Jim Walls holds a patent titled "Memory cell retention enhancement through erase state modification." This patent describes a method of controlling a resistive memory cell. A resistance threshold value is defined for the memory cell, wherein a circuit identifies the cell as erased if a detected resistance of the cell is above the resistance threshold and identifies the cell as programmed if the detected resistance is below the resistance threshold value. A filament is formed across an electrolyte switching region of the cell by applying an electrical charge, wherein the cell having the formed filament has a first resistance. The cell is then erased to an erased state having a second resistance greater than the first resistance. The cell is then programmed to a quasi-erased state having a third resistance between the first and second resistances, and above the resistance threshold value such that the cell is identified by the circuit as erased. The cell may then be maintained in the quasi-erased state.
