An electronic circuit 100 and manufacturing method comprising a resistive element, 1a-g, having a first resistance, and irradiating at least a part of the resistive element with electromagnetic radiation (7, figure 3) to change the resistance of the resistive element (1, figure 3) from the first to a second resistance, lower than the first resistance. The electronic circuit may comprise an electrically insulating material transparent to visible light covering a semiconducting resistive element whose conductivity changes with applied irradiation (figures 3,4 & 7). Irradiation might originate from a lamp or a laser. The resistive element may also be pre heated to a temperature of 100 degree C prior to irradiation. The circuit may include a display 4 to show the state of the resistive elements 1a-g. A method of storing the data is also disclosed comprising: receiving a piece of data to be stored; determining a number according to the data; and irradiating at least part of a resistive element with that number of pulses of electromagnetic radiation to change a resistance of the resistive element from a first resistance to a second resistance, (lower than the first). A difference between the first resistance and the second resistance is dependent on the number. The active resistive element may comprise IGZO (Indium gallium zinc oxide), the insulating material may comprise Aluminum Oxide, Al2O3. |
