Abstract: A method of controlling a resistive memory cell is provided. 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.

Abstract: A line frequency monitoring and load shedding control apparatus is placed in or closely coupled to a power load and monitors the line frequency of the alternating current electric power source supplying the power load. When a decrease in line frequency is detected, this line frequency monitoring and load shedding control apparatus may interrupt certain portions of the power load, thereby allowing the power source frequency to stabilize. Subsequently, the line frequency monitoring and load shedding control apparatus makes a determination to return operation of the load that was shed to a normal state of operation as the power line frequency recovers to a normal operating frequency. Fixed time delays, e.g., adjustable, programmable, etc., and/or pseudo random time delays may be incorporated to sequentially reconnect the loads back onto the power source, thereby preventing the loads previously shed from being reconnected all at the same time.
