Abstract
In a semiconductor memory cell in which binary data is represented by the density of minority carriers stored in the inversion regions of two isolated MIS capacitors, a method of nondestructively recalling the datum stored therein is described. In this method, the minority carriers are extracted from either one or both of the inversion regions, and the resulting potential change across either one or both of the MIS capacitors is indicative of the datum stored in the memory cell. These memory cells can be used in random access memories with nondestructive recall and in content addressable memories.
