  • Publication number: 20190066777
    Abstract: Systems, apparatuses, and methods for generating a reference voltage are described. In various embodiments, an interface between a memory and a processor uses a reference voltage generator to generate a reference voltage for a single pin or a small group of pins. The generator generates a default reference voltage from a first tap in a resistor ladder, injects current with a current controller into a second tap of the resistor ladder when the generator receives an indication to generate a larger reference voltage, and draws current from a third tap of the resistor ladder when the generator receives an indication to generate a smaller reference voltage. The generator also generates a high threshold voltage independent of a low threshold voltage after calibration.

  • Publication number: 20170249985
    Abstract: A current sense amplifier may include one or more clamping circuits coupled between differential output nodes of the amplifier. The clamping circuits may be enabled during at least a portion of the time that the sense amplifier is sensing the state of a memory cell coupled to a differential input of the sense amplifier. The clamping circuits may be disabled during the time that the sense amplifier is sensing the state of a memory cell at different times in a staggered manner. The clamping circuits may be effecting in making the current sense amplifier less sensitive to noise signals.

  • Patent number: 9644312
    Abstract: Disclosed is a synthetic leather produced by directly coating a water-soluble synthetic resin solution on the surface of a fabric to form a film thereon such that fine gaps formed on the fabric are partially left open to have a certain degree of air permeability. In particular, a brushing process is used for brushing the surface of a fabric using a brushing machine to raise a nap. Next, a hydrolysis-resistant and flame-retardant resin solution is coated on the back of the fabric, which is opposite to the surface on which the nap is raised, to reinforce the back of the fabric. A film forming process then applies a water-soluble polyurethane resin solution to the nap raised on the surface of the fabric to form a film on the surface of the fabric thereby producing a synthetic leather product that has air permeability properties that are superior to genuine leather.
