  • Fluid ejection device
    Patent number: 7815273
    Abstract: A fluid ejection device includes groups of firing cells, sharing a common fire signal and a common address selection mechanism, each firing cell having a drop generator for ejecting fluid and a dynamic memory addressable by the common address selection mechanism. Circuitry interfaces with the firing cells to allow the capture of data during two consecutive select cycles, then firing of all cells during a third cycle.
