Abstract :
The authors describe the design and fabrication results for a 185 K×6-bit field memory which is suitable for storing TV signals. This device offers an efficient and economical architecture for storing one field of NTSC signals on a single chip. It permits 3-fsc sampling and 6-bit quantization and contains all address-generating and refresh control circuits. Continuous read and write operation with a 60-ns cycle time, refresh-free operation, and 0.5-H jump function enhance the system performance. Standard cell design methodology is adopted to comply quickly with customer´s requests
