A fluid ejection assembly includes a fluid slot, a recirculation channel, and a drop ejection element within the recirculation channel. A pump element is configured to pump fluid to and from the fluid slot through the recirculation channel. A first addressable drive circuit associated with the drop ejection element and a second addressable drive circuit associated with the pump element are capable of driving the drop ejection element and the pump element simultaneously.
