Beschreibung
Zusammenfassung:	The present disclosure is directed to a microfluidic die that includes ejection circuitry and one time programmable memory with a minimal number of contact pads to external devices. The die includes a relatively large number of nozzles and a relatively small number of contact pads. The die includes decoding circuitry that utilizes the small number of contact pads to control the drive and ejection of the nozzles and the reading/writing of the memory with the same contact pads.
