摘要： A field-programmable redundancy apparatus for integrated circuit semiconductor memory arrays is disclosed. The present invention allows the user to replace a defective memory cell with a redundant memory cell while the integrated circuit memory array is in the field. The user communicates with the redundancy apparatus over standard signal paths of the integrated circuit semiconductor memory array and with standard voltage levels. The redundancy apparatus detects a predetermined code sequence on one or more of the address and data lines of the memory array to enter a special redundancy-reconfiguration mode. In the reconfiguration mode, the redundancy apparatus provides information on the availability and functionality of the redundant memory cells and enables the user to replace a defective memory cell with a selected redundant memory cell. The field-programmable redundancy apparatus may comprise nonvolatile memory means, such as EEPROM's, to store the replacements of primary memory cells with redundant memory cells. In the reconfiguration mode, detection of a second predetermined code sequence causes the reconfiguration mode to be exited.

摘要： A protective coating for a metal substrate is provided that is light, durable, galvanically protective, and easily applied at the site of manufacture. The coating has at least two layers, one of which is a galvanizing layer and one of which is a micro-composite of a galvanic metal and a non-conducting material, such as polymer. Such coatings are useful for example to protect pipes or other metal surfaces in corrosive environments. Methods of producing the coating are provided, including methods that use advanced spraying techniques to provide very thin but consistent layers. Using the advanced spraying methods the composite layer can be created by co-spraying the galvanic metal and the nonconductive material onto the surface of the galvanic coating. Optionally, an outer coat of insulating material can be applied to provide further protection to the surface.

摘要： A floating gate circuit having a floating gate and a level shift circuit. A first tunneling device formed between a first and second tunnel electrode is included for removing electrons from the floating gate. Electrons are injected onto the floating gate without the use of a tunneling device, e.g., using avalanche injection. A first circuit is coupled to the floating gate for generating an output voltage at an output terminal. The level shift circuit has a second tunnel device coupled between the output terminal and the first tunnel electrode. The second tunnel device is for tracking changes in the characteristics of the first tunneling device connected to the floating gate. The level shift circuit level shifts the output of the floating gate circuit to a voltage that enables the tunnel device coupled to a floating gate to precisely set the floating gate to a desired voltage during a set mode.

摘要： A mechanical pipe joint, restraining gasket, and method for restraining pipe spigots within adjacent bell sockets. The restraining gasket is composed of two axially-separate components: a sealing portion and a restraining portion made of a plurality of arcuate locking members. The restraining gasket and a gland surround an outer surface of the pipe spigot. The mechanical pipe joint is formed as the pipe spigot is inserted into the bell socket and the gland is axially attached to the bell socket so that the restraining gasket is held between: the gland, an inner surface of the bell socket, and the outer surface of the pipe spigot, so as to provide a fluid seal in the joint and urge the locking members into contact with the outer surface of the pipe spigot, axially restraining the pipe spigot within the bell socket.

摘要： A method and apparatus for setting a floating gate in a floating gate circuit using dual conduction of Fowler-Nordheim tunnel devices is disclosed. In one embodiment, the present invention comprises a floating gate circuit having a single floating gate. During a set mode, the charge level on the floating gate is modified until it is set to a predetermined charge level that is a function of an input set voltage. In another embodiment, the floating gate circuit comprises two floating gates. During a set mode the charge level on each of the floating gates is modified until the difference in charge level between the two floating gates is a predetermined function of an input set voltage that is capacitively coupled to one of the floating gates during the set mode.

摘要： A current metering circuit is configured as a single stage charge pump for limiting the current level applied to the tunneling regions of an integrated circuit, nonvolatile, floating gate memory cell. The current metering circuit includes a storage capacitor which has one plate pumped by a periodic signal. The other plate of the capacitor is charged from a voltage that is boot-strapped from the voltage that presently exists across the active tunneling region. More particularly, a high voltage is applied to the drain of a transistor whose gate is connected to the tunneling region. The source of this transistor is coupled to a plate of the storage capacitor. This source develops a voltage equal to the present voltage across the load less the turnon threshold of the transistor. When the periodic signal goes low, the storage capacitor is charged from the voltage appearing at the source of this transistor. When the periodic signal goes high, this transistor is biased to turn off and the capacitor discharges through a diode to develop the metered output current. The current amplitude is equal to the product of the capacitance of the storage capacitor, the change in voltage across the capacitor in each cycle and the frequency of the periodic signal.
