ABSTRACT:
In a method and a device for storing analog signals in integrated circuit elements, the memory elements are constituted by field-effect transistors having a number of layers of different dielectrics between the gate and the doped semiconductor substrate of the transistor. After discrete sampling of the analog signal has been performed at N points, the N amplitudes corresponding to the N points are stored in N transistors in the form of a threshold voltage.
