摘要： A content addressable memory device based on an extremely compact design, potentially as small as 16F2 per memory cell. One embodiment is based on cells having two memory storage elements, such as RRAM elements. Each RRAM element and a respective FET are connected in series between a common matchline and a respective bitline. Cell content for each cell is matched against a bit of a search word by applying voltages to the respective bitlines dependent upon bit value and causing one of the two RRAM elements for each cell to discharge the matchline over a low resistance path in event of mismatch between the cell content and the bit. If no “quick” discharge occurs for multiple cells of a row, then a match is detected. In addition, a matchline recharge path to a high voltage bitline is substantially eliminated by controlling the FETs with specific wordline voltages.

摘要： A resistive change memory device includes a first conductive line, a second conductive line, and a resistive change memory cell that includes a resistive memory element coupled between the first conductive line and the second conductive line. The resistive change memory device also includes control circuitry to apply, via the first conductive line and the second conductive line, a first biasing condition to the resistive change memory cell for a reset operation and a second biasing condition to the resistive change memory cell for a restore operation. The restore operation is performed to counteract a decrease in resistance of the resistive memory element for a reset state of the resistive change memory cell. At least one of a voltage, current, and duration of the second biasing condition is greater than a corresponding voltage, current, or duration of the first biasing condition.

摘要： A micro-relay module includes a substrate and a lid in spaced apart relation, and a solder ring which bonds the lid to the substrate to define a chamber therebetween. A micromachined relay is integrally formed on the substrate or on the lid within the chamber. A gas is contained in the chamber at a gas pressure which is above atmospheric pressure. Input/output pads are included outside the chamber and electrically connected to the micromachined relay. Large numbers of encapsulated modules may be fabricated on a single substrate by integrally forming an array of relays on a face of a first substrate. A second substrate is placed adjacent the face with a corresponding array of solder rings therebetween, such that a respective solder ring surrounds a respective relay. The solder rings are reflowed in a gas atmosphere which is above atmospheric pressure to thereby form an array of high pressure gas encapsulating chambers. The first and second substrates are then singulated for form a plurality of individual micro-relay modules.

摘要： A method for fabricating solder bumps on a microelectronic device having contact pads includes the steps of depositing a titanium barrier layer on the device, forming an under bump metallurgy layer on the titanium barrier layer, and forming one or more solder bumps on the under bump metallurgy layer. The solder bump or bumps define exposed portions of the under bump metallurgy layer which are removed, and then the exposed portion of the titanium barrier layer is removed. The titanium barrier layer protects the underlying microelectronic device from the etchants used to remove the under bump metallurgy layer. The titanium layer also prevents the under bump metallurgy layer from forming a residue on the underlying microelectronic device. Accordingly, the titanium barrier layer allows the under bump metallurgy layer to be quickly removed without leaving residual matter thereby reducing the possibility of electrical shorts between solder bumps.

摘要： Thin layers of aluminum (13) and palladium (12) are deposited and annealed to produce aluminum-palladium alloy (14). The surface of the alloy (14) is exposed and treated with an aluminum etchant to produce a catalytic surface (15). The catalytic surface is used for electroless plating of nickel, providing excellent plating uniformity and adhesion, as well as a reduced plating induction time. Several variants of the basic method are possible.

摘要： An electrically and mechanically robust microelectromechanical transducer is formed of a pleated dielectric sheet having patterned electrical conductors on the opposing faces thereof. The pleats define a plurality of spaced apart walls, with each wall including an electrically conductive portion at one side thereof. Positive and negative voltages, applied to opposite faces of the pleated sheet, cause the walls to move towards one another by electrostatic attraction. The walls can also move away from one another by electrostatic repulsion upon application of appropriate voltages. The microelectromechanical transducer may be fabricated by fabricating a sheet with integral pleats or by forming a "self-pleating" flat sheet which forms pleats after conductor fabrication thereon.

摘要： A resistance memory includes a resistance memory cell having a resistance memory element and a two-terminal access device in series. The two-terminal access device affects the current-voltage characteristic of the resistance memory cell. The resistance memory additionally includes a circuit to apply across the resistance memory cell a set pulse having a set polarity to set the resistance memory cell to a low-resistance state that is retained after application of the set pulse, a reset pulse having a reset polarity, opposite to the set polarity, to reset the resistance memory cell to a high-resistance state that is retained after application of the reset pulse, and a read pulse of the reset polarity and smaller in magnitude than the reset pulse to determine the resistance state of the resistance memory cell without changing the resistance state of the resistance memory cell.

摘要： A transistor includes a substrate having a surface, where a first region and a second region of the substrate are doped with a first type of dopant, and where a third region of the substrate between the first region and the second region is doped with a second type of dopant. An insulator layer is deposited above a portion of the surface, which includes the third region, and a gate layer is deposited above the insulator layer. An encapsulation layer encloses ends of the gate layer, thereby defining gaps between ends of the insulator layer and the encapsulation layer. These gaps have a depth relative to the ends of the gate layer, with one end of the insulator layer proximate to a boundary between the first region and the third region and another end of the insulator layer proximate to a boundary between the second region and the third region.
