Electrochemical memory cells

Principles of writing and reading the data in a binary code in memory cells based on electrochemical cells are considered. The realization of a multib it cell with a liquid electrolyte, where the data are written by a successi ve cathodic deposition of alternating metallic layers with different electr ochemical properties and thicknesses on the working electrode, is shown. Th e layer deposition can be controlled by current or voltage pulses of differ ent amplitudes and lengths. The written data are read on the basis of a suc cessive controlled anodic dissolution of the multilayer structures. Attaina ble parameters of the electrochemical memory of an integral design combinin g a multicell memory and a controller on the same crystal are estimated.
