摘要: Different embodiments of a one-time-programmable antifuse cell included. 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.

摘要: 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.

摘要: Some embodiments provide a memory cell comprising a body region doped with charge carriers of a first type, a source region disposed in the body region and doped with charge carriers of a second type, and a drain region disposed in the body region and doped with charge carriers of the second type. According to some embodiments, the body region, the source region, and the drain region are oriented in a first direction, the body region and the source region form a first junction, and the body region and the drain region form a second junction. Moreover, 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. Some embodiments further include a transistor oriented in a second direction, wherein the second direction is not parallel to the first direction.

摘要: 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.
