    Abstract: In some examples, a system includes a plurality of fluid ejection devices, a fluid ejection controller, and a plurality of data lines shared by the plurality of fluid ejection devices and connected between the fluid ejection controller and the plurality of fluid ejection devices. A first data line of the plurality of data lines communicates data of a first memory of a first fluid ejection device of the plurality of fluid ejection devices, and a second data line of the plurality of data lines communicates data of a second memory of the first fluid ejection device.

    IPC: B41J2/045

    Abstract: In some examples, a circuit for use with a memory element and a nozzle for outputting fluid, includes a data line, a fire line, and a selector responsive to the data line to select the memory element or the nozzle. The selector is to select the memory element responsive to the data line having a first value, and to select the nozzle responsive to the data line having a second value different from the first value. The fire line is to control activation of the nozzle in response to the nozzle being selected by the selector, and to communicate data of the memory element in response to the memory element being selected by the selector.
