Abstract: Operating a selector device that controls access of a signal to a memory element may comprise applying a main operating voltage pulse and a refresh voltage pulse to the selector device. The refresh voltage pulse and main operating voltage pulse have opposite polarities. A magnitude of the main operating voltage pulse is greater than or equal to a threshold voltage for turning on the selector device, and a maximum magnitude of the refresh voltage pulse is less than the threshold voltage. The refresh voltage pulse reduces a difference between the threshold voltage and a turn-off voltage of the selector device, and may be applied immediately before or immediately after the main operating voltage pulse. An electronic circuit may include the selector device and a driving circuit for apply the pulses. A nonvolatile memory may include the driving circuit and a plurality of nonvolatile memory elements each including a selector device.

Abstract: A system and method for delivering moving route prediction-based content is provided, in terms of a server, as a user terminal allows producing an image at the future time point, at the user's final position, which is predicted, based on a total delay time of a network, rather than producing images at every time point, it is possible to reduce the data amount required for creating the content, and as the image produced at the user's final position according to the user moving route is stored in the buffer, it is possible to provide smooth content service without delay. In addition, the user may experience virtual reality as a 360° image suitable for the user's moving position from the user's point of view is played through a HMD of the user terminal S1, and the user may also use a lively content by making the 360° image stereoscopic.
