    摘要: A system includes a pull-up circuit to program a memory cell. The pull-up circuit may include a level shifter to receive a control signal, a supply voltage, and one or more of a plurality of rail voltages, each of the plurality of rail voltages substantially equal to a respective integer multiple of the supply voltage, and to generate a second control signal, and a cascode stage. The cascode stage may include a plurality of transistors, a gate voltage of each of the plurality of transistors to be controlled at least in part by a respective one of the second control signal, the supply voltage, and at least one of the plurality of rail voltages, and an output node to provide a cell programming signal.

    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.
