  • Video field memory device for multi-broadcasting system and manufacturing method therefor
    Patent number: 5353120
    Abstract: A video field memory device for multi-broadcasting system employs upper and lower half memory cell arrays for storing a video signal according to the largest scanning bit and the largest scanning line of the multi-broadcasting system, and the upper and lower half memory cell arrays having the scanning bits of 1023.times.4 and the scanning lines of 313.times.4 corresponding to the largest one of various television broadcasting systems. Thus, the video field memory device for multi-broadcasting system for varying the scanning bits or the scanning lines can select a broadcasting system in a single chip by using a external TYPE signal, independent of the scanning bits or the scanning lines for each television broadcasting system.
