  • High speed computer data transfer system
    Patent number: 4992678
    Abstract: A high speed computer data transfer system includes a clamping circuit for limiting pre-charge voltages in the case where multiple pre-charge cycles occur before a pull-down operation. Data bus voltage swings between logic high and logic low levels as well as pull-down times are reduced, thus lowering the time needed to transfer the data. The preferred embodiment is implemented using complementary metal-oxide-semiconductor (CMOS) technology.
