  • 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.

  • 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.

  • 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.

  • Publication number: 20060067133
    Abstract: A method and apparatus for a one-phase write to a one-transistor memory cell array. In one embodiment, the method includes a one-phase write to a selected wordline of a memory cell array. Once the wordline is selected, a logical zero value is stored within at least one memory cell of the selected wordline of the memory cell array. Simultaneously, a logical 0 value is stored within at least one memory cell of the selected wordline of the selected memory cell array. Other embodiments are described and claimed.

  • Publication number: 20060067109
    Abstract: A method is described that comprises modulating the power consumption of an SRAM as a function of its usage at least by reaching, with help of a transistor, a voltage on a node within an operational amplifier's feedback loop. The voltage is beyond another voltage that the operational amplifier would drive the node to be without the help of the transistor. The voltage helps the feedback loop establish a voltage drop across a cell within the SRAM.
