Dynamic memory based firing cell for thermal ink jet printhead |
摘要 |
A dynamic memory based integrated circuit ink jet firing cell that includes a heater resistor, a drive transistor, and a dynamic memory circuit for storing firing data only for such heater resistor. Also disclosed is an integrated circuit firing array that includes a plurality of dynamic memory based firing cells divided into a plurality of fire groups of firing cells, each fire group having a plurality of subgroups; data lines for providing energizing data to the firing cells; control lines for providing control information to the firing cells wherein all firing cells within a subgroup are connected to a common subset of the control lines so as to be controlled to concurrently store energizing data; and a plurality fire lines for supplying energizing energy to the firing cells, wherein all firing cells of a fire group receive energizing energy from only one fire line.
