Abstract: The present disclosure discloses a memory access interface device. A clock generation circuit generates reference signals. A transmitter transmits an output command and address signal to a memory device according to the reference signals. A signal training circuit executes a training process in a training mode that includes steps outlined below. A training signal is generated such that the training signal is transmitted as the output command and address signal. The training signal and the data signal generated by the memory device are compared to generate a comparison result indicating whether the data signal matches the training signal. The comparison result is stored. The clock generation circuit is controlled to modify a phase of at least one of the reference signals to be one of a plurality of under-test phases to execute a new loop of the training process until all the under-test phases are trained.

Abstract: The present disclosure discloses a memory access interface device. A clock generation circuit generates reference clock signals. Each of access signal transmission circuits each includes a duty cycle adjusting circuit, a duty cycle detection circuit, a frequency division circuit and an asynchronous first-in-first-out circuit. The duty cycle adjusting circuit performs duty cycle adjustment on one of the reference clock signals according to a duty cycle detection signal to generate an output clock signal having a duty cycle. The duty cycle detection circuit detects a variation of the duty cycle to generate the duty cycle detection signal. The frequency division circuit divides a frequency of the output clock signal to generate a read clock signal. The asynchronous first-in-first-out circuit receives an access signal from a memory access controller and outputs an output access signal according to the read clock signal to access the memory device accordingly.

Abstract: In a method for controlling a car using a car key, a selected function is received from a function menu displayed on an operation interface of a display device of the car key. System data about the car is acquired from a management unit of the car, and devices of the car are controlled using the management unit, according to the selected function. The system data about the car or status of the devices of the car is displayed on the operation interface of the display device.

Abstract: A method for managing icons of a home screen using an electronic device displays a tab widget to switch among panels of the home screen on a touchscreen of the electronic device. The tab widget including customized icons that represent the plurality of panels correspondingly. The tab widget is displayed on each of the panels of the home screen. A dragging operation on a target icon of a current panel of the home screen is detected. A target panel is determined if the target icon has been dragged to one of the customized icons in the tab widget, and the target panel corresponds to the customized icon. The target icon is moved from the current panel to the target panel if the target panel is not the current panel and the target panel has enough display space to position the target icon.

Abstract: An indicator light includes a first ring shaped light and a second ring shaped light. The first ring shaped light is divided into two first curved lights. One of the first curved lights is configured to indicate a system status of an electronic device. The other one of the first curved lights is configured to indicate a connection status of a network of the electronic device. The second ring shaped light is configured to indicate a working status of at least one data storage device of the electronic device.
