Fluid ejection device

A method for ejecting fluid from a fluid ejection device, the method comprising:

• receiving, in a printhead die, energy signals having energy pulses at firing cells including a first bank of firing cells and a second bank of firing cells;
• receiving, in the printhead die, control signals;
• providing, in the printhead die, in response to the control signals, all of a first group of address signals to the first bank of firing cells;
• providing, in the printhead die, in response to the control signals, all of the first group of address signals to the second bank of firing cells;
• selectively providing, in the printhead die, in response to the control signals, a first sequence of varying first address signals in the first group of address signals to enable only the first bank of firing cells for activation;
• and
• selectively providing, in the printhead die, in response to the control signals, a second sequence of varying second address signals in the first group of address signals to enable only the second bank of firing cells for activation, wherein the second sequence of varying second address signals is selectively provided independent of the first sequence of varying first address signals.

A fluid ejection device comprising:

• fire lines configured to receive energy signals having energy pulses;
• firing cells including a first bank of firing cells and a second bank of firing cells, wherein the firing cells are configured to receive the energy signals;
• and
• a first address generator configured to respond to control signals to selectively provide a first sequence of varying first address signals adapted to enable the first bank of firing cells for activation and a second sequence of varying second address signals adapted to enable the second bank of firing cells for activation, wherein the second sequence of varying second address signals is selectively provided independent of the first sequence of varying first address signals and the control signals comprise control pulses and a series of timing pulses and the first address generator is configured to initiate the first sequence in response to receiving a first control pulse in the control pulses coincident with a first timing pulse in the series of timing pulses and the first address generator further comprises:
• a direction circuit configured to set a first direction signal in response to receiving a second control pulse in the control pulses coincident with a second timing pulse in the series of timing pulses and the direction circuit receives a third timing pulse in the series of timing pulses and responds to the third timing pulse to set a second direction signal.
