Abstract: An improved integrated circuit area efficient redundancy multiplexer circuit technique provides similar functionality to conventional CMOS transmission, or “pass” gates while concomitantly reducing circuit complexity, the die area necessary to support redundant elements and complementary control signals in memory device ICs and undesired parasitic capacitance. The technique of the present invention effectuates this end by utilizing the on-chip boosted voltage levels (Vpp) which are generally available in integrated circuit memory devices to supply the voltage for the control signal applied to a single N-channel transistor pass gate instead of the conventional supply voltage level of Vcc. The Vpp voltage and circuit ground (“GND”) are then utilized as the logic “high” and “low” signal levels respectively. This use is made possible due to the fact that these control signals operate at a direct current (“DC”) level after device power-up.

Abstract: A local write driver circuit for an integrated circuit device memory array which requires only a single write enable signal to couple complimentary data signals between global and local write data lines thereby obviating the need to provide complementary write enable signals as in conventional implementations. By eliminating the need for a second complementary write enable signal line, less on-chip die area is required for the signal path along with a concomitant reduction in power requirements due to the fact that there is one less line which has to switch during a given write cycle.

Abstract: Methods and compositions are disclosed for controlled addition of components that decrease the viscosity of the viscoelastic surfactant fluids or for controlled changes in the electrolyte concentration or composition of the viscoelastic surfactant fluids. One aspect of the invention relates to the use of internal breakers with a delayed activation. Another aspect of the invention relates to the use of precursors that release a breaking system such as alcohol by a process such as melting, slow dissolution, reaction with a compound present in the fluid or added to the fluid during or after the step of injecting, rupture of an encapsulating coating and de-adsorption of a breaking agent absorbed into solid particles. In another aspect of the invention, alcohols are included in a pad to reduce the low-shear viscosity and reduce the resistance to flow of the treatment fluids during a desired phase of the treatment.

Abstract: A sliding vehicle storage system is described for mounting on two opposing interior side walls of a vehicle. The storage system provides for a platform slidingly received in a vehicle which may be positioned at different heights in relation to the side walls of a vehicle to provide versatility in use. The storage system includes, in relation to each of two opposing interior side walls, mounting means attached to a support assembly. Each support assembly includes a mounting plate connected to an outer track assembly including a plurality of wheel bearings held operatively in place within the outer track assembly, and a locking plate. An inner track assembly slidingly mates with the outer track assembly. A cross member support is connected to the inner track assembly. Extending between the two inner track assemblies upon the two opposing vehicle side walls are at least two cross members supported by the cross member support of each opposing support assembly.

Abstract: A single level gate NVM device (20) includes a floating gate FET (11) and a capacitor (12) fabricated in two P-wells (27, 28) formed in an N-epitaxial layer (22) on a P-substrate (21). P+ sinkers (29, 31) and N-type buried layers (25, 26) provide isolation between the two P-wells (27, 28). The NVM device (20) is programmed or erased by biasing the FET (11) and the capacitor (12) to move charge carriers onto or away from a conductive layer (36) which serves as a floating gate (14) of the FET (11). Data is read from the NVM device (20) by sensing a current flowing in the FET (11) while applying a reading voltage to the capacitor (12).

Abstract: An integrated circuit having a first and second bond pads, a latch circuit, and a voltage lead. Different configurations of the internal circuitry of the integrated circuit are selected by applying the voltage lead either to the first or second bond pads. This result is achieved because the latch circuit, coupled between the first and second bond pads, is capable of inverting the voltage response seen at the first bond pad.

Abstract: A circuit and method for a memory device, such as a synchronous dynamic random access memory (SDRAM) having at least two memory banks. Columns of at least two memory banks are concurrently addressable to permit data to be written to, or read from, the at least two memory banks concurrently. By writing data concurrently to more than one memory bank, testing of the memory of the memory device can be effectuated in a reduced period of time. Data can also be written or read from a single bank in a multi-bank RAM without requiring that a particular bank be specified during a read/write command.

Abstract: A roll-type toilet tissue is formed of three layers, with one layer being formed by a hemorrhoid-treating medication and being sandwiched between two other layers.

Abstract: A transpolarizer is employed as a programmable capacitance divider. Two ferroelectric capacitors are coupled in series to form a common node and two extreme poles. The polarization of the two capacitors is set by grounding the two poles and then bringing them both up to VCC while impressing a voltage at the common node corresponding to data to be stored. Therefore, while one pole is held at VSS, the other pole is pulsed from VSS to VCC with the common node floating. A voltage develops at the common node which is above or below the midpoint between VSS and VCC, and will be indicative of the stored data. The capacitance divider is programmed in accordance with data. One such divider is added to a DRAM memory cell to form a shadow DRAM cell. Two such dividers are added to a static RAM memory cell to form a shadow static RAM cell. The same divider arrangement is operable in both volatile and non-volatile modes. An improvement arises by using PZT as dielectric in 54:46 mole ratio.
