Abstract :
A complete one-transistor dynamic RAM cell in GaAs is discussed. Read and write operations is monitored by observing the capacitance of the storage node. Storage times on the order of a few seconds are obtained at room temperature with an activation energy slightly less than half the zero-temperature bandgap.<>
