Abstract: An earphone plug applicable to different system specifications includes a terminal and a switch device. The earphone plug is inserted into an earphone jack of an external electronic device for transmitting signals by a plurality of exposed signal interfaces of the terminal. The switch device combined with the terminal has a first conductor and a second conductor. When the switch device is switched between a first mode and a second mode, the first conductor and the second conductor alternately contact with two of the signal interfaces. Thus, the signal transmission defined by the signal interfaces is changed and the earphone plug is applicable to electronic devices with different system specifications.

Abstract: A data access method for accessing a rewritable non-volatile memory module via a data bus through a first and a second thread module, and a memory controller and a memory storage apparatus using the same are provided. In the present method, an access executing right is assigned to the second thread module to write page data. Whether an access command to be executed by the first thread module is received is determined when the second thread module writes a predetermined amount of page data into a predetermined number of physical pages. The access executing right is assigned to the first thread module when the access command is received, so that the first thread module executes the access command in a foreground mode and the second thread module executes an ongoing task in a background mode. Thereby, timeout caused by delayed response of the first thread module is effectively avoided.
