  • Patent number: 7501316
    Abstract: Some embodiments provide a memory cell that includes a body region, a source region and a drain region. The body region is doped with charge carriers of a first type, the source region is disposed in the body region and doped with charge carriers of a second type, and the drain region is disposed in the body region and doped with charge carriers of the second type. The body region and the source region form a first junction, the body region and the drain region form a second junction, and a conductivity of the first junction from the body region to the source region in a case that the first junction is unbiased is substantially less than a conductivity of the second junction from the body region to the drain region in a case that the second junction is unbiased.

  • Patent number: 7391640
    Abstract: A dynamic random access memory includes a cell having a circuit between a floating-body transistor and a bit line. Activation of the circuit is controlled to provide isolation between the floating body and bit-line voltage both during write operations and during times when the cell is unselected. The added isolation improves performance, for example, by reducing the need for gate-to-body coupling and the magnitude of voltage swings between the bit lines.

  • Patent number: 7280425
    Abstract: A one-time programmable (OTP) cell includes an access transistor coupled to an antifuse transistor. 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.

  • 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.
