A single-transistor random access memory (RAM) cell may be used as universal memory. The single-transistor RAM cell generally includes a first gate, a 2D-crystal channel, a source, a drain, an ion conductor, and a second (back) gate. The single-transistor RAM cell is capable of drifting ions towards the graphene channel. The ions in turn induce charge carriers from the source into the graphene channel. The closer the ions are to the graphene channel, the higher the conductivity of the graphene channel. As the ions are spaced from the graphene channel, the conductivity of the graphene channel is reduced. Thus the presence of the charged ions adjacent to the channel is used to modify the channel's conductivity, which is sensed to indicate the state of the memory.
