Abstract

A memory apparatus has a plurality of first electrodes and at least one second electrode separated by an electrolyte solution. Information may be recorded by causing an electrical current to flow between a selected of the first electrodes and the second electrode to deposit an electrochemically active material on one of the selected first or the second electrodes. A method for recording and reading information has steps of writing the information by causing a current to flow between a first and a second electrode through an electrolyte solution to cause an electrochemically active material to electrodeposit, and reading the information by sensing the deposited material with a sensor.
