Abstract
An electronic device, such as an opto-electronic device and an integrated semiconductor memory device, includes at least one integrated memory point structure including a quantum well semiconductor area buried in the substrate of the structure and disposed under the insulated gate of a transistor. A biasing voltage source is adapted to bias the structure to enable charging or discharging of charges in the quantum well or outside the quantum well.
