    摘要: The present invention discloses a DRAM cell utilizing floating body effect and a manufacturing method thereof. The DRAM cell includes a P type semiconductor region provided on a buried oxide layer, an N type semiconductor region provided on the P type semiconductor region, a gate region provided on the N type semiconductor region, and an electrical isolation region surrounding the P type semiconductor region and the N type semiconductor region. A diode of floating body effect is taken as a storage node. Via a tunneling effect between bands, electrons gather in the floating body, which is defined as a first storage state; via forward bias of PN junction, electrons are emitted out from the floating body or holes are injected into the floating body, which is defined as a second storage state. The present invention provides a highly efficient DRAM cell utilizing floating body effect with high density, which has low power consumption, has simple manufacturing process, and is compatible to the conventional CMOS and conventional logic circuit manufacturing process.

    摘要: 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 (V.sub.f) of the tunnel diode (32) controls the V.sub.gs transfer curve (56) of the load transistor.

    摘要: The invention relates to a tunnel diode provided with two metallically conducting electrodes (1, 2) with an insulating dielectric (3) in between, which forms a barrier with a barrier level for electrons and which has a thickness such that electrons can tunnel through the barrier from the one to the other electrode. Such a tunnel diode has the disadvantage that it has no memory. In many applications it is desirable for the tunnel diode to hold a certain switching state, such as open/closed. According to the invention, the tunnel diode is characterized in that the dielectric (3) comprises a layer of a material which is ferroelectric at room temperature with a remanent polarization which influences the barrier level. It is achieved thereby that the tunnel diode has various switching states in dependence on the remanent polarization of the dielectric (3). The switching state is maintained until the polarization of the dielectric (3) changes.
