Abstract
A latch circuit has a tri-state gate and a reverse tri-state gate that share the same complementary controls. The reverse tri-state gate locks an output of the tri-state gate when the tri-state gate is shut-off. The complementary control signals include a first undoped polysilicon strip. The output of the reverse tri-state gate may be coupled to the output of the tri-state gate via a second undoped polysilicon strip.
