    摘要: A single-poly EEPROM cell comprising an inverter and a capacitive coupling area. The inverter is formed by: a p-well formed in a substrate; a gate structure formed atop the p-well and being formed from a thin gate oxide layer underneath a conductive layer; an n-base formed adjacent to a first edge of the gate structure and within the p-well; a p+ structure formed within the n-base; and a n+ structure adjacent a second edge of the gate structure and within the p-well. The capacitive coupling area is formed from a second p-well formed in the substrate and a floating gate, the floating gate formed from the conductive layer and capacitively coupled to the second p-well.

    摘要: A MOSFET structure that utilizes self-aligned polysilicon and/or buried diffusion lines for coupling capacitors, provides a threshold voltage V.sub.T that is tunable from the control gate from positive (enhancement) to negative (depletion) by applying V.sub.cc to the bias gate and carefully designing the coupling ratio of the control gate and the bias gate. This scheme provides multiple V.sub.T 's on-chip without process complexity.

    摘要: A single-poly neuron transistor is formed by utilizing a series of doped substrate regions in lieu of the input gates that are conventionally used to form neuron transistors. With conventional neuron transistors, the input gates are isolated from the floating gate by a layer of interpoly dielectric. In the present invention, the series of doped substrate regions are isolated from the floating gate by a layer of gate oxide.
