Abstract
A fluid ejection device comprising an identification line adapted to receive a program signal and a read signal and identification cells electrically coupled to the identification line. Each of the identification cells comprises a memory circuit and a memory element. The memory circuit is adapted to receive and respond to signals in order to selectively store a value in the memory circuit, which determines whether the identification cell is responsive to signals received on the identification line.
