Abstract: Disclosed is an operating method of an electronic device which includes a semiconductor memory having a plurality of resistive storage cells. The operating method may include: writing data to the resistive storage cells using a write current of a set condition; determining whether the writing of data to the resistive storage cells is successful, wherein the writing of data is determined to be failed when the number of resistive storage cells with failed writing of data exceeds a reference value, and successful when the number of resistive storage cells with failed writing of data is equal to or less than the reference value; strengthening the set condition when the writing of data is determined to be failed; and easing the set condition when the writing of data is determined to be successful.

Abstract: A data format is provided for song accompaniment which includes pointers indicating a starting position of accompaniment data and lyrics data in every section of a song is provided. The data format includes a lyrics data portion having lyrics data; an accompaniment data portion having accompaniment data corresponding to the lyrics data of the lyrics data portion; and a header portion having a plurality of pointer pairs, each pointer pair being composed of one pointer indicating the front position of each section in the lyrics data of the lyrics data portion and the other pointer indicating the front position of accompaniment data corresponding to the front position of each section. The data format has a header portion including pointers indicating the starting position of a section, thereby allowing the synchronization of the lyrics and accompaniment data of every section during the reproduction of a data format.

Abstract: A video-song accompaniment apparatus includes an accompaniment information memory storing accompaniment information of a song in a musical instrument digital interface (MIDI) format, a lyrics information memory storing lyrics information of the song, an accompaniment signal generator for generating an accompaniment signal according to the accompaniment information, a lyrics signal generator for generating a video character signal according to the lyrics information, a controller for providing the lyrics information to the lyrics signal generator and the accompaniment information to the accompaniment signal generator, respectively, to thereby generate the lyrics information in synchronization with the accompaniment information. The apparatus includes an instrument selector for input of instrument selection information to the controller.

Abstract: A compact disk, a high-speed searching method of the compact disk, and a recording method which corresponds to the high-speed searching method is provided. The compact disk includes a lead-in area and e program area. The lead-in area contains table-of-contents information which includes the number of recording tracks recorded on the disk and address information relating to each track. The program area contains index-table information which includes index numbers and starting addresses for a plurality of programs recorded on the disk. Furthermore, the plurality of programs are recorded in the program area according to its corresponding index number. Specifically, the programs are recorded from the innermost circumference to the outermost circumference of the disk in a tree structure based on the index numbers.

Abstract: A method of displaying a title and lyrics of the first measure of a reserved song before the end of a currently performed song includes steps for calculating remaining time by comparing total performance time with an elapsed time of a currently performed song, obtaining a title and lyrics information for the first measure of the reserved song responsive to a reserved song number when the remaining time is less than a predetermined value, and displaying the title and the lyrics information superimposed on a background image associated with the currently performed song. The method for displaying title and lyrics information using a video-song accompaniment apparatus enhances user convenience by displaying the title and associated lyrics for the first measure of a reserved song for verification before a currently performed song ends. A video-song accompaniment apparatus capable of performing this method is also described.
