ABSTRACT:
This fast-access data storage circuit is made of a semiconductor material with a two-dimensional carrier gas between two of its layers. The material is rendered superconducting by a suitable choice of the temperature and magnetic field conditions. The circuit is formed by a plurality of memory cells, each of which is formed by two selection transistors, a semiconductor loop, ohmic contacts and a grid which is arranged on the loop and one of the contacts. The superconductivity reduces the access time. One selection controls the reading of data or the writing of a state "1" in the loop, while the other selection transistor controls the cancellation of the data and hence the writing of a state "0" by means of the grid arranged on the loop.
