Abstract

1,006,458. Tunnel diode matrix stores. STANDARD TELEPHONES & CABLES Ltd. Feb. 1, 1963 [Feb. 3, 1962], No. 4261/63. Heading G4C. [Also in Division H3] A storage matrix is formed from circuit elements (see Division H3) comprising a tunnel diode TD fed from a constant current source and having in parallel an inductor L and an ordinary diode D or a similar non-linear resistor. The arrangement is such that the characteristics of the two diodes are as shown in Fig. 2b so that the circuit element has two stable operating points 1 and 2. Storage is effected by applying half-current pulses simultaneously to the required row and column lines X, Y and reading out is effected by applying a small current pulse to a row line to produce an output pulse in the common inductor L of those tunnel diodes which, because they are in the high voltage condition, permit the corresponding diode D to conduct. Clearing of the information is effected by interrupting the bias current Io.
