  • Patent number: 7299078
    Abstract: A mobile terminal includes a speaker arrangement for providing surround sound. The terminal includes a folder hinged at a main body and having an LCD attached thereto, speakers mounted at the folder and implementing a three-dimensional surround-sound effect, and a sliding unit for sliding at least one of the speakers when the speakers produce the three-dimensional surround-sound effect. Because the distance between the speakers can be widened according to a user's selection, three-dimensional surround-sound can be maximized and thus product quality can be significantly enhanced.

  • Patent number: 6960805
    Abstract: The present invention relates to a flash memory cell and method of manufacturing the same, and programming/erasing/reading method in the flash memory cell. According to the present invention, a source region and a drain region are first formed and a tunnel oxide film is then formed. Therefore, it is possible to prevent damage of the tunnel oxide film due to an ion implantation process. Further, independent two channel regions are formed below the floating gate. Thus, it is possible to store data of two or more bits at a single cell. In addition, the tunnel oxide film, the floating gate and the dielectric film having an ONO structure are formed at a given regions. It is thus possible to reduce the steps of a process and improve an electrical characteristic and integration level of a device.

  • Patent number: 6583465
    Abstract: There is disclosed a code addressable memory (“CAM”) cell in a flash memory device. In order to stabilize the operation of the CAM cell in a flash memory device operating at a low voltage, the present invention manufactures a CAM cell in which a floating gate is formed to extend on more than two active regions and more than two cell arrays are connected in parallel commonly using a source region and a drain region. Therefore, the present invention can increase the gate-coupling ration of the CAM cell, thus stabilizing the operation of the CAM cell at a device for low-voltage use.
