Appl. No.:

8/458780

Inventors:

Song C. Kim - Austin TX
Kuan-Yu J. Lin - Austin TX

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H03K 190948
H03K 19096

US Classification:

326121

Abstract:

Logic circuitry utilizing the advantages of static and dynamic design techniques utilize feed-forward from the inputs to the logic circuit and feed-back from the output of the logic circuit in order to provide a RESET signal to precharge the logic circuit to a predetermined state. This technique also provides for initialization of the circuit before the arrival of data input signals.

International Classification:

H03K 3027

US Classification:

327200

Abstract:

The present invention is directed to an apparatus for precharging complementary data circuits. The apparatus comprises two hold circuits, one for storing the data and the other for storing its complement. A signal for initiates precharging the hold circuits to the same signal level, where the signal for initiating the precharging of the hold circuits is dependent on the hold circuits' outputs.
