Currents so low that the magnetic field generated around the conducting film is below the coercive fields will not change the magnetization direction even in the film with the low coercive field.

20100074037 | CONTROL VOLTAGE TRACKING CIRCUITS, METHODS FOR RECORDING A CONTROL VOLTAGE FOR A CLOCK SYNCHRONIZATION CIRCUIT AND METHODS FOR SETTING A VOLTAGE CONTROLLED DELAY - Memories, clock synchronization circuits, clock synchronization controller circuits, and methods for setting a voltage controlled delay of a clock synchronization circuit and tracking and recording the control voltage are disclosed. For example, a clock synchronization controller provides an initial control voltage to the voltage controlled delay during initialization of the synchronization circuit until a phase dependent control voltage stabilizes. The stable phase dependent control voltage is substituted for the initial control voltage. Following stabilization of the phase dependent control voltage, a phase detector of the clock synchronization circuit is activated. A recovery control voltage is provided by the clock synchronization controller to the voltage controlled delay during recovery of the clock synchronization from a power-saving mode until the phase dependent control voltage stabilizes. | 2010-03-25 |
