Abstract
Single bipolar transistor memory cell in which information is stored on the collector to substrate capacitance. This capacitance may be enhanced by an additional diffused region. Storage and retrieval of information is accomplished through only two leads connected to the transistor which is operated so that a portion of the base is fully depleted during a portion of the operating memory cycle of the memory cell.
