    摘要: A single-poly PMOS nonvolatile memory (NVM) cell and a method of programming, erasing and reading such a cell are implemented using a single-poly PMOS NVM cell which includes a floating gate injection transistor, a select switch, and a tunneling capacitor having one plate in common with the floating gate of the injection transistor. Methods of altering the number of electrons on the floating gate of the single-poly PMOS NVM cell are used which, with appropriate biasing of the components permit the power terminals of the cell to have appropriate voltages applied to thereby avoid stuck bits and induce hot electrons onto the floating gate of the NVM cell.

    摘要: Methods and apparatuses prevent overtunneling in nonvolatile floating gate memory (NVM) cells. An individual cell includes a circuit with a transistor that has a floating gate that stores charge, and a capacitor structure for extracting charge from the gate, such as by tunneling. A counteracting circuit prevents extracting charge from the floating gate beyond a threshold, therefore preventing overtunneling or correcting for it. In one embodiment, the counteracting circuit supplies electrons to the floating gate, to compensate for tunneling beyond a point. In another embodiment, the counteracting circuit includes a switch, and a sensor to trigger the switch when the appropriate threshold is reached. The switch may be arranged in any number of suitable ways, such as to prevent a high voltage from being applied to the capacitor structure, or to prevent a power supply from being applied to a terminal of the transistor or to a well of the transistor.

    摘要: Methods and apparatuses prevent overtunneling in pFET-based nonvolatile floating gate memory (NVM) cells. During a tunneling process, in which charge carriers are removed from a floating gate of a pFET-based NVM cell, a channel current of a memory cell transistor is monitored and compared to a predetermined minimum channel current required to maintain a conducting channel in an injection transistor of the memory cell. When the monitored channel current drops below the predetermined minimum channel current, charge carriers are injected onto the floating gate by impact-ionized hot-electron injection (IHEI) so that overtunneling is avoided.

    摘要: RFID tags and chips for RFID tags are capable of being inventoried in one or more early attempts. These tags are capable of then refraining from participating in one or more subsequent inventorying attempts. In some embodiments refraining is performed solely by the tag, while in others it is guided by the RFID reader. In some embodiments, an inventoried indicator in the tag becomes updated upon backscattering. The updated value is used by the tag to recognize a subsequent attempt, and thus refrain from participating in it. This permits the subsequent attempt to be used more intensively for inventorying the more elusive, harder-to-read tags, especially in more demanding scenarios.
