摘要： According to a method of programming a nonvolatile memory device, a program operation is performed on a first page by applying a program pulse to the first page. A verification operation is performed on the program operation by applying a verification voltage to the first page. If the program operation for the first page has not been completed, a voltage selected from threshold voltages of the first page is set as a highest threshold voltage. The program operation for the first page is completed by repeatedly performing a program operation and a verification operation on the first page while a voltage level of the program pulse is increased. The sum of a program start voltage for the first page and a difference between the verification voltage and the highest threshold voltage is set as a program start voltage for a second page.

摘要： Provided is an apparatus for transferring optical data in an optical switching system using time synchronization. The apparatus performs time synchronization on optical data to input the optical data at regular intervals through fiber delay line for time synchronization respectively disposed on input ports. Therefore, the apparatus can efficiently reduce a data blocking rate in comparison with a conventional optical switching system using an asynchronous electric buffer without a synchronous process, and achieve the same performance as conventional asynchronous technology despite using fewer wavelength converters and buffers, thus reducing system cost. In addition, using dynamic time synchronization modules, the apparatus performs time synchronization for minute time variation due to an environment such as temperature.

摘要： A packaged semiconductor device (a wafer-level chip scale package) containing a conductive adhesive material as an electrical interconnect route between the semiconductor die and a patterned conductive substrate is described. The patterned conductive substrate acts not only as a substrate, but also as a redistribution layer that converts the dense pad layout of the die to a larger array configuration of the solder balls in the circuit board. Using the invention allows the formation of a lower priced chip scale package that also overcomes the restriction of the die size used in die-sized chip packages and the input-output pattern that can be required by the printed circuit board. Thus, the invention can provide a familiar pitch (i.e., interface) to the printed circuit board for any small die.

摘要： An apparatus and method for transferring optical data in an optical switching system are provided. When optical data input to a node are in contention, the optical data are converted from optical signals to electrical signals and temporarily stored. When an output resource is available, the stored optical data are converted to the available output resource and transmitted to a desired destination node. This overcomes the buffering depth limit that is observed when a conventional optical fiber delay line is used. Accordingly, an optical data loss rate can be reduced such that optical data can be efficiently transferred. Further, non-contending optical data are directly delivered to output resource by the switching unit, thereby reducing the cost of optical/electrical conversion and wavelength conversion and enabling the apparatus to be implemented at low cost.
