  • Publication number: 20060092742
    Abstract: Different embodiments of a one-time-programmable antifuse cell are provided in this disclosure. In one embodiment, a circuit is provided that includes an antifuse element, a high voltage device, and a sense circuit. The antifuse element has a voltage supply terminal to be at a sense voltage during sensing/reading and a higher programming voltage during programming. The sense circuit is configured to enable programming the antifuse element during programming and to sense the state of the antifuse element during sensing. The high voltage device is coupled between the antifuse element and the sense circuit to couple the antifuse element to the sense circuit during programming and sensing and to protectively shield the sense circuit from the higher programming voltage during programming.

  • Publication number: 20060091896
    Abstract: A method is described that comprises flowing current from one region of a coil to another region of the coil. The flowing induces—through flux linkage—a voltage across a second coil. A second current substantially does not flow through the second coil. The method also includes measuring the current with a first voltage at the another region of the coil and a second voltage at the second coil.

  • Patent number: 7031203
    Abstract: A DRAM memory cell uses a single transistor to perform the data storage and switching functions of a conventional cell. The transistor has a floating channel body which stores a potential that corresponds to one of two digital data values. The transistor further includes a gate connected to a first word line, a drain connected to a second word line, and a source connected to a bit line. By setting the word and bit lines to specific voltage states, the channel body stores a digital one potential as a result of impact ionization and a digital zero value as a result of forward bias of body-to-source junction.

  • Patent number: 7030676
    Abstract: A timing circuit independently controls placement of the positive and negative edges of a periodic signal. This signal may then be used to control a wide variety of integrated circuit applications. The timing circuit includes separate programmable delay lines and a signal processor. Each delay line delays an input clock signal by a different increment of time. The signal processor then generates a timing signal from the clock signal, where the timing signal has a first edge controlled by the first delayed clock signal and a second edge controlled by the second delayed clock signal. The edges may be controlled so that the timing signal assumes different logical values for different amounts of time, thereby customizing the signal to any application. An example of one application includes using the timing signal control switching in a DC-DC converter.

  • Publication number: 20060071646
    Abstract: A method is described that induced dielectric breakdown within a capacitor's dielectric material while driving a current through the capacitor. The current is specific to data that is being written into the capacitor. The method also involves reading the data by interpreting behavior of the capacitor that is determined by the capacitor's resistance, where, the capacitor's resistance is a consequence of the inducing and the driving.
