Abstract: A memory device may include an access transistor, and a memory cell configured to store an item of information. The memory cell may include first and second electrodes configured to have different optoelectronic states corresponding respectively to two values of the item of information, and to switch between the different optoelectronic states based upon a control signal external to the memory cell, the different optoelectronic states being naturally stable in an absence of the control signal. The memory cell may also include a solid electrolyte between the first and second electrodes.
