  • Patent number: 7206249
    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.

  • Publication number: 20070076463
    Abstract: According to embodiments of the present invention, a one-time programmable (OTP) cell includes an access transistor coupled to an antifuse transistor. In on embodiment, access transistor has a gate oxide thickness that is greater than the gate oxide thickness of the antifuse transistor so that if the antifuse transistor is programmed, the voltage felt across the gate/drain junction of the access transistor is insufficient to cause the gate oxide of the access transistor to break down. The dual gate oxide OTP cell may be used in an array in which only one OTP cell is programmed at a time. The dual gate oxide OTP cell also may be used in an array in which several OTP cells are programmed simultaneously.
