摘要:
A flip-flop has an output control node and an isolation switch selectively couples a retention sense node to the output control node. A sense circuit selectively couples an external sense current source to the retention sense node and to magnetic tunneling junction (MTJ) elements. Optionally a write circuit selectively injects a write current through one MTJ element and then another MTJ element. Optionally, a write circuit injects a write current through a first MTJ element concurrently with injecting a write current through a second MTJ element.

A resistance-based memory with a reduced voltage I/O device is disclosed. In a particular embodiment, a circuit includes a data path including a first resistive memory cell and a first load transistor. A reference path includes a second resistive memory cell and a second load transistor. The first load transistor and the second load transistor are input and output (I/O) transistors adapted to operate at a load supply voltage similar to a core supply voltage of a core transistor within the circuit.

A resistance based memory sensing circuit has reference current transistors feeding a reference node and a read current transistor feeding a sense node, each transistor has a substrate body at a regular substrate voltage during a stand-by mode and biased during a sensing mode at a body bias voltage lower than the regular substrate voltage. In one option the body bias voltage is determined by a reference voltage on the reference node. The substrate body at the regular substrate voltage causes the transistors to have a regular threshold voltage, and the substrate body at the body bias voltage causes the transistors to have a sense mode threshold voltage, lower than the regular threshold voltage.

A non-volatile latch circuit includes a pair of cross-coupled inverters, a pair of resistance-based memory elements, and write circuitry configured to write data to the pair of resistance-based memory elements. The pair of resistance-based memory elements is isolated from the pair of cross-coupled inverters during a latching operation. A sensing circuit includes a first current path that includes a first resistance-based memory element and an output of the sensing circuit. The sensing circuit includes a second current path to reduce current flow through the first resistance-based memory element at a first operating point of the sensing circuit. The sensing circuit may also include an n-type metal-oxide-semiconductor (NMOS) transistor to provide a step down supply voltage to the first current path.

A safety razor blade tool includes a substantially rectangular safety razor blade having a cutting edge and an opposing non-cutting edge, and a rubberized thermoplastic protective cover fixedly attached to the non-cutting edge. The protective cover has an extruded substantially rigid inner layer of thermoplastic material and a coextruded thermoplastic rubber outer layer. Such an improved safety razor blade tool may be produced by providing a blade having a cutting edge and a non-cutting edge, feeding a substantially rigid thermoplastic in a viscous state to a coextrusion die, simultaneously feeding a thermoplastic rubber compatible with the substantially rigid thermoplastic in a viscous state to the same coextrusion die, coextruding the substantially rigid thermoplastic and the compatible thermoplastic rubber to form a one-piece coextruded protective cover having an inner layer of the substantially rigid thermoplastic and an outer layer of the compatible thermoplastic rubber, and fixedly attaching the coextruded one-piece protective cover to the non-cutting edge of the blade.

The present invention relates to a composition which reduces the measurement error caused by the effect of hematocrit in a biosensor and to a biosensor comprising the same. Specifically, the invention relates to a reagent composition comprising an enzyme, an electron transfer mediator, a water-soluble polymer, and bile acid, and to a biosensor comprising a reagent layer formed of the composition. The reagent layer reduces the measurement error caused by the effect of hematocrit in the biosensor.
