Abstract: A wireless charging seat of a mobile device includes a seat body comprised of two integral and forwardly extended primary placing platforms and a floor end portion, a rear folding and clamping plate disposed at an end surface of an oblique end portion, a receiving and clamping space defined between the rear folding and clamping plate and a rear surface of the oblique end portion for clamping a charging coil, a clamping storage slot formed at an appropriate position of both sides of the rear folding and clamping plate separately for plugging and storing two auxiliary support members, corresponding plug slots formed on both sides of the bottom proximate to the oblique end portion, for selectively plugging the auxiliary support members to form an additional placing platform with a raised position.

Abstract: A method for operating a memory device that comprises periodically generating a refresh request signal for performing a refresh operation, providing an access request signal for performing an access operation, performing the refresh operation if the refresh request signal occurs prior to the access request signal, and performing the access operation if the access request signal occurs prior to the refresh request signal.

Abstract: A method of operating a memory device including an array of cells formed in rows and columns that comprises providing a control signal, activating the control signal, the activated control signal including a first state and a second state, continuously performing access cycles in response to the first state of the activated control signal in one part of a period, and continuously performing refresh cycles in response to the second state of the activated control signal in another part of the period.
