Abstract: A differential sensing content addressable memory cell without any word lines connected to the cells in the same row comprises a first bit line for supplying a first bit. A first storage element has a first phase change resistor for storing a first stored bit, which is connected in series with a first diode. The first storage element is connected to the first bit line. A second bit line supplies a second bit, with the second bit being an inverse of the first bit. A second storage element has a second phase change resistor for storing a second stored bit, which is connected in series with a second diode. The second storage element is connected to the second bit line. A match line is connected to the first and second storage elements for indicating whether a match occurred between the first bit and the first stored bit, and between the second bit and the second stored bit

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).

Abstract: A method for partial local self-boosting of a memory cell channel is disclosed. As a part of memory cell channel partial local self-boosting, an isolating memory cell located on a source side of a program inhibited memory cell is turned off and a gating memory cell located on a drain side of the program inhibited memory cell is used to pass a pre-charge voltage to the program inhibited memory cell to provide a pre-charge voltage to a channel of the program inhibited memory cell. Moreover, a pre-charge voltage is passed to a buffering memory cell located on the source side of the program inhibited memory cell to provide a pre-charge voltage to a channel of the buffering memory cell and the gating memory cell that is located on the drain side of the program inhibited memory cell is turned off. During programming, a program voltage is applied to the gate of the program inhibited memory cell where a channel voltage of the program inhibited memory cell is raised above a level raised by the pre-charge voltage.
