Patent ID: 8907428

Claim:
A circuit comprising: a first transistor of a first type; a second transistor of the first type; a first transistor of a second type; a second transistor of the second type; a third transistor of the second type; and a fourth transistor of the second type; wherein the first transistor of the first type, the second transistor of the first type, the first transistor of the second type, and the second transistor of the second type form a cross latch having a first node and a second node; a first terminal of the third transistor of the second type is coupled with the first node; a first terminal of the fourth transistor of the second type is coupled with the second node; and at least one of a second terminal of the third transistor of the second type or a second terminal of the fourth transistor of the second type is configured to receive a signal that is not directly from a power source and is sufficient to turn off the third transistor or the fourth transistor.
