Abstract
An electronic matrix system and method for rapidly storing and efficiently retaining electric charge in selected ones of a plurality of storage elements are disclosed. Each storage element is addressable through a pair of parallel row select address lines and a column address line. A pair of threshold devices are coupled in nonopposing relation between the row select address lines and the storage element is coupled between the common node of the threshold devices and the column address line to which charging potential is applied. During the charging of the storage element, operating potentials which are substantially equal and opposite in polarity are applied to the row select line pair to forward bias both threshold devices and thereafter operating potentials which are also substantially equal and opposite in polarity are applied to the row select line pair to back bias both threshold devices to provide retention of the charge in the storage element.
