  • High speed output buffer with reduced voltage bounce and no cross current
    Patent number: 5367205
    Abstract: There is an output buffer which reduces the amount of voltage bounce occurring during the switching of the outputted signal. Uniquely, there is an output buffer/driver which turns on either driver transistor by progressively increasing the voltage on the control gates in a series of steps. Additionally, and simultaneously, the complementary signal is turned off immediately to prevent any possibility of creating current crossing in the output driver. Additionally, the invention has the advantage of avoiding cross current from occurring during switching of the output signals.

  • Zero power reprogrammable flash cell for a programmable logic device
    Patent number: 5324998
    Abstract: There is a zero power reprogrammable flash cell for a programmable logic device. Specifically, there is a PLD capable of "zero power" during the standby period, being capable of functioning within around a 10 nanosecond time frame, and having programmable OR arrays. Uniquely, the subject invention is capable of using only microamps of power during standby periods. The use of a flash transistor enables reprogrammability of the PLD.
