Video field memory device for multi-broadcasting system and manufacturing method therefor

A video field memory device for a multi-broadcasting system, comprising:

• upper and lower memory cell arrays according to a largest scanning bit and a largest scanning line for multi-broadcasting systems for storing an image memory;
• data write registers for writing a serial input data in parallel, said serial input data being provided through a data input buffer to a data line of said upper and lower memory cell arrays;
• write data pointers for assigning write bit points to said data write registers;
• read data registers for serially reading parallel data provided to either address line of said upper or lower half memory cell array through a data read output buffer;
• read data pointers for assigning read bit points to said read data registers;
• a line address decoder for decoding read address lines and write address lines of said upper and lower half memory cell arrays by a read address pointer, a write address pointer, and a refresh address pointer according to a predetermined sequence;
• and
• an address input circuit for controlling said respective address pointer.
