    Abstract: A flash memory cell is of the type having a substrate of a first conductivity type having a first region of a second conductivity type at a first end, and a second region of the second conductivity type at a second end, spaced apart from the first end, with a channel region between the first end and the second end, a floating gate insulated from a first portion of the channel region and adjacent to the second region, a first control gate adjacent to the floating gate and insulated therefrom, and insulated from a second portion of the channel region, and adjacent to the first region, a second control gate capacitively coupled to the floating gate, and positioned over the floating gate. A method programming the cell to one of a plurality of MLC states comprises applying a current source to the first region. A first voltage is applied to the first control gate sufficient to turn on the second portion of the channel region. A second voltage is applied to the second region, sufficient to cause electrons to flow from the first region towards the second region. A third voltage is applied to the second control gate sufficient to cause electrons in the channel region to be injected onto the floating gate. The third voltage is applied uninterrupted until the floating gate is programmed to the one state.

    Abstract: A nonvolatile reprogrammable switch for use in a PLD or FPGA has a nonvolatile memory cell connected to the gate of an MOS transistor with the terminals of the MOS transistor connected to the source of the signal and to the circuit. The nonvolatile memory cell is of a split gate type having a floating gate positioned over a first portion of the channel and a control gate positioned over a second portion of the channel with electrons being injected onto the floating gate by hot electron injection mechanism. The nonvolatile memory cell is erased by the action of the electrons from the floating gate being tunneled through Fowler-Nordheim tunneling onto the control gate, which is adjacent to the second region. As a result, no high voltage is ever applied to the second region during program or erase. Thus, the nonvolatile memory cell with the second region can be connected directly to the gate of the MOS transistor, which together therewith forms a nonvolatile reprogrammable switch.

    Abstract: A method of trimming down the volume of a semiconductor resistor element using electrical resistance feedback. After forming conductive material disposed between a pair of electrodes, a voltage is applied to the electrodes to produce an electrical current through the conductive material sufficient to heat and melt away a portion of the conductive material. By reducing the volume of the conductive material, its resistance is increased. The application of the voltage is ceased once the desired dimensions (and thus resistivity) of the conductive material is reached. The resulting semiconductor resistor element could have a fixed resistance, or could have a variable resistance (by using phase change memory material).

A first electrical contact is on the second surface of the dielectric/heater layer. A second electrical contact is on the second surface of the phase changing chalcogenide material. A third electrical contact is on the second surface of the phase changing chalcogenide material, spaced apart from the second electrical contact. The switching device can be programmed such that the channel length separation between the second electrical contact and the third electrical contact on the phase changing chalcogenide material is changed to represent the desired state to be stored in the device.

    Abstract: An integrated circuit programmable resistor or programmable capacitor has a floating gate memory cell connected either in series or in parallel to a fixed resistor or a fixed capacitor. The resistance or the capacitance of the floating gate memory cell can be changed by the amount of charge stored on the floating gate which affects the resistance or the capacitance of the channel from which the floating gate is spaced apart. A particular application of the programmable resistor/capacitor is used in a system whereby the resistance or the capacitance can be change or fine tuned as a result of either drift caused by time or by operating conditions such as temperature. Thus, the temperature of the substrate in which the floating gate memory cell is fabricated can be monitored and the resistance or the capacitance of the floating gate memory cell changed dynamically.

    Abstract: A method of forming an array of floating gate memory cells, and an array formed thereby, wherein a trench is formed into a surface of a semiconductor substrate. The source region is formed underneath the trench, the drain region is formed along the substrate surface, and the channel region therebetween includes a first portion extending vertically along the trench sidewall and a second portion extending horizontally along the substrate surface. The floating gate is disposed in the trench adjacent to and insulated from the channel region first portion. The control gate is disposed over and insulated from the channel region second portion. The trench sidewall meets the substrate surface at an acute angle to form a sharp edge. The channel region second portion extends from the second region in a direction toward the sharp edge and the floating gate to define a path for programming the floating gate with electrons via hot electron injection.

    Abstract: A method of forming a floating gate memory cell array, and the array formed thereby, wherein a trench is formed into the surface of a semiconductor substrate. The source and drain regions are formed underneath the trench and along the substrate surface, respectively, with a non-linear channel region therebetween. The floating gate has a lower portion disposed in the trench and an upper portion disposed above the substrate surface and having a lateral protrusion extending parallel to the substrate surface. The lateral protrusion is formed by etching a cavity into an exposed end of a sacrificial layer and filling it with polysilicon. The control gate is formed about the lateral protrusion and is insulated therefrom. The trench sidewall meets the substrate surface at an acute angle to form a sharp edge that points toward the floating gate and in a direction opposite to that of the lateral protrusion.
