dispositivo de ejeção de fluído

摘要

A fluid ejection device comprising an identification line (402) adapted to receive a program signal and a read signal and identification cells (400) electrically coupled to the identification line (402). Each of the identification cells (400) 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.
