Abstract: A device (2) with a switchable capacitance comprises a first and a second electrode (12, 20) facing each other, a dielectric layer (14) between a first and a second capacitor electrode (12, 20), and a switching member (18) between the second electrode (20) and the dielectric layer (14), the switching member (18) comprising a switching material reversibly switchable between a lower conductivity state and a higher conductivity state, each of the lower conductivity state and the higher conductivity state being persistent, wherein the capacitance of the device (2) depends on the conductivity state of the switching material.

Abstract: A method for changing an operation performed by an electronic device includes defining a process flow chart of the operation to be performed by the electronic device, the process flow chart having one or more primitive actions, the operation having one or more components, the primitive action operating on the components to produce an output. The method further includes determining a number of information dispersal units for each of the components. For each of the components, defining a set of information dispersal units, transforming one or more of the primitive actions of the operation using a transform function to create a transformed primitive action, and applying each of the transformed primitive actions to all the respective sets of information dispersal units to produce a transformed set of transformed information dispersal units.
