    • A static RAM memory cell (30) uses cross-coupled enhancement mode, N-channel MOS drive transistors (36) to form a bistable flip-flop. A load circuit (34) couples between I/O ports (40) of the drive transistors (36) and Vcc. For each drive transistor (36), the load circuit includes a depletion mode, N-channel MOS load transistor (54) and a forward biased tunnel diode (32). The drain and gate of the load transistor (54) couple across the anode and cathode of the tunnel diode (32) so that the forward voltage (Vf) of the tunnel diode (32) controls the Vgs transfer curve (56) of the load transistor.

    • A static RAM memory cell (30) uses cross-coupled enhancement mode, N-channel MOD drive transistors (36) to form a bistable flip-flop. A load circuit (34) couples between I/O ports (40) of the drive transistors (36) and Vcc. For each drive transistor (36), the load circuit includes a depletion mode, N-channel MOS load transistor (54) and a forward biased tunnel diode (32). The drain and gate of the load transistor (54) couple across the anode and cathode of the tunnel diode (32) so that the forward voltage (Vf) of the tunnel diode (32) controls the Vgs transfer curve (56) of the load transistor. The tunnel diode (32) may be formed at a junction between a mono-crystalline silicon layer (88) at a region (98, 100) which also serves as a source or drain of a transistor (36, 54) and a poly-crystalline silicon layer (106). The poly-crystalline silicon layer (106) also serves as a non-metallic, conductive interconnection (55) to save space.

    • PROBLEM TO BE SOLVED: To provide an element structure suitable for a high integration by realizing compatibility of a high speed operation and a low power consumption difficult in a conventional memory cell using a negative differentiating resistor and a load. SOLUTION: In a gate oxide film formed on a surface of a silicon substrate, a film on a source region is thinned. A first p type polycrystal silicon film, a tunnel oxide film and a second p type polycrystalline silicon film are sequentially laminated on a gate region. A source and the first silicon film constitute a high concentration impurity pn junction via a thin silicon oxide film to become an Esaki diode exhibiting the negative differentiating resistor. Meanwhile, a part between the first silicon film and the second silicon film becomes a nonlinear tunnel resistor to perform a role of load. The negative differentiating resistor and the load are connected in series between a low-voltage power source (ground) and a high-voltage power source Vdd to constitute a transistor containing a bistable circuit. Since potential information of the first silicon film of a memory node is read by a transistor amplification, it is rapid. Meanwhile, a current flowing between the power sources is suppressed to a low value, and a low power consumption at a waiting time is performed. An SRAM cell can be constituted of two elements with an excellent integration.
