  • ROM with four-phase dynamic circuits
    Patent number: 6157562
    Abstract: The invention relates to a ROM with four-phase dynamic circuits, featuring at a concept of four-phase operation by fusing and combining pseudo-domino dynamic circuits as well as skill of HS-PDCMOS dynamic circuits. Meanwhile, the invention has improved HS-PDCMOS concept circuit for use in a ROM. Analysis and simulation reveal that the invention is advantageous not only in keeping a compact circuit area but also in evaluation speed and in reducing power dissipation for a ROM.
