Abstract
A bidirectional shift register includes a plurality of serially connected cells with each cell having a first circuit portion and a second circuit portion. Each circuit portion includes at least two parallel inverters connected in opposite directions. The relative transconductance of the oppositely connected inverters in each circuit portion of a cell can be varied thereby determining the direction of data flow through the circuit portion and through the bidirectional shift register.
