Abstract: A magnetic device includes a seed pattern, a reference magnetic structure on the seed pattern, a free magnetic pattern on the reference magnetic structure, and a tunnel barrier between the reference magnetic structure and the free magnetic pattern. The reference magnetic structure includes a synthetic antiferromagnetic (SAF) structure including a first fixed pattern in contact with an upper surface of the seed pattern, an antiferromagnetic coupling pattern in contact with an upper surface of the first fixed pattern, and a second fixed pattern in contact with an upper surface of the antiferromagnetic coupling pattern; a nonmagnetic pattern in contact with an upper surface of the second fixed pattern; and a polarization reinforcement magnetic pattern in contact with an upper surface of the nonmagnetic pattern.

Abstract: A system-on-chip includes: a dynamic power monitor configured to generate a power detection signal by calculating an amount of power consumed by a functional circuit in real time; a frequency controller configured to detect an idle period and a running period of the functional circuit in response to the power detection signal, and generate a clock control signal based on the power detection signal; and a clock controller configured to change a frequency of a clock signal provided to the functional circuit, based on the clock control signal. The running period includes: a first running period in which the frequency of the clock signal has a first value based on the clock control signal; and a second running period in which the frequency of the clock signal has a second value that is greater than the first value based on the clock control signal.

Abstract: An electronic device and a method control applications in the electronic device. A plurality of applications are executed in a foreground and a background. The number of touch points input to a touch screen are detected to select an application according to the detected number of the touch points. A touch gesture is detected for controlling the selected application, and the selected application is controlled according to the detected touch gesture.
