发明名称 Dynamic memory based firing cell for thermal ink jet printhead
摘要 <p>A dynamic memory based integrated circuit ink jet firing cell that includes a heater resistor (21), a drive transistor (101), and a dynamic memory circuit (62) 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 (100, 200, 300) divided into a plurality of fire groups (W, X, Y, Z) of firing cells, each fire group having a plurality of subgroups; data lines (D0:D15, ~D0:~D15) 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 (FIRE_W, FIRE_X, FIRE_Y, FIRE_Z) for supplying energizing energy to the firing cells, wherein all firing cells of a fire group receive energizing energy from only one fire line. </p>
