Abstract

1,081,570. Tunnel diode circuits. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 29, 1966 [April 2, 1965], No. 13895/66. Heading H3T. [Also in Division G4] A tunnel diode memory cell in which the tunnel diode 4, the anode of which is earthed and the cathode of which is biased for the diode to have two stable states, is connected to a coaxial cable 10 which reverses the input of the cell, and is also connected through a charge storage diode 14 to the output of the cell, and through a diode 20 to an energization circuit for the cell. Such cells may be used to form a ring counter. When tunnel diode 4 is in its lowvoltage state, representing " O," a positive energization pulse from source 34 is insufficient to cause diode 20 to conduct, and the cell is unaffected. When tunnel diode 4 is in its high voltage state, representing " 1," the positive energization pulse passes to diode 4 through diode 20 to switch diode 4 to its low-voltage state " O," and also through charge storage diode 14 (because of the charge stored therein during the period preceding the pulse) and through the reversing cable of the succeeding cell to switch it from " 0 " to " 1." Each cell may be provided with an output circuit 24, S to indicate the state of that cell.
