A current sense resistor integrated with an integrated circuit die where the integrated circuit die is housed in a flip-chip semiconductor package includes a metal layer formed over a passivation layer of the integrated circuit die where the metal layer having an array of metal pillars extending therefrom. The use of DMA increases data transfer speed, while freeing the system processor to perform other tasks, including compressingdecompressing the data transferred to and from the disk. The plurality of progressive jackpots can be arranged in columns and rows of a matrix, or can be displayed with other characteristics for identification, such as color, shapes, or alpha-numeric characters. Conversely, the potential level at the side of the Hi and potential level of the power source line are made to be changed by the respective corresponding colors when a transistor which controls current supplied to a light emitting element is an n-channel type. The traveler rollers may include a plurality of rollers movable about a load-bearing member.
