Abstract
A memory for non-volatile recording, lasting a long time, of fast signals. It comprises two storage stages: The first stage enables the input signal to be recorded by the production of depletion zones in a semiconductor; The second stage is formed by an MIIS type element whose charge is controlled by the extent of the preceding depletion zone, and ensures long recording of the signal.
