Abstract
An integrated circuit to drive a number of fluid actuation devices, comprising a circuit configured to have a memory access state which can be set to one of an enabled state and disabled state. The integrated circuit to include a fluid actuation circuit to transmit selection information for a fluid actuation device, the selection information comprising a data state bit. The integrated circuit to include a memory cell array, configured so that each memory cell is accessible by the memory access state being enabled, and the data state bit being set.
Claims19
A fluid ejection device comprising:
- a circuit having a memory access state that is set to one of an enabled state and disabled state, the circuit including a storage element having a memory access bit that when set configures the memory access state of the circuit to the enabled state;
- a fluid actuation circuit to transmit selection information for a fluid actuation device of a plurality of fluid actuation devices, the selection information to control a dispersion of fluid through the fluid actuation device and including a data state bit;
- and
- a memory cell array with a memory cell that is accessible by the memory access state being set to the enabled state and the data state bit being set, wherein a memory state bit, a configuration state bit, and the data state bit are received over a same interface pad.
A method for driving a plurality of fluid actuation devices in a fluid ejection device, comprising:
- configuring an integrated circuit in the fluid ejection device to have a memory access state which can be set to one of an enabled state and disabled state, the integrated circuit including a storage element having a memory access bit that when set configures the memory access state of the integrated circuit to the enabled state;
- transmitting, with a fluid actuation circuit, selection information for a fluid actuation device of the plurality of fluid actuation devices, the selection information to control a dispersion of fluid through the fluid actuation device and comprising a data state bit;
- and
- configuring a memory cell array in the memory cell array to be accessible by the memory access state when set to the enabled state, and the data state bit being set, wherein a memory state bit, a configuration state bit, and the data state bit are received over a same interface pad.
A fluid ejection device comprising:
- a memory circuit with a memory access state that can be set to one of an enabled state and disabled state, the memory circuit including a storage element having a memory access bit that when set configures the memory access state of the memory circuit to the enabled state;
- a fluid actuation circuit to transmit selection information for a fluid actuation device of a plurality of fluid actuation devices, the selection information to control a dispersion of fluid through the fluid actuation device and including a data state bit that when set is to cause setting of the memory access bit;
- and
- a memory cell array with a memory cell that is accessible by the memory access state being set to the enabled state responsive to the data state bit being set, wherein a memory state bit, a configuration state bit, and the data state bit are received over a same interface pad.
