Abstract: An integrated circuit to drive a plurality of fluid actuation devices includes a plurality of memory cells, a select circuit, configuration logic, and control logic. Each memory cell corresponds to a fluid actuation device. The select circuit selects fluid actuation devices and memory cells corresponding to the selected fluid actuation devices. The configuration logic enables or disables access to the plurality of memory cells. The control logic either activates the selected fluid actuation devices or accesses the memory cells corresponding to the selected fluid actuation devices based on a state of the configuration logic.
