Abstract: A fluid ejection controller interface includes input logic to receive control data packets and a first clock signal, each control data packet including a set of primitive data bits and a set of random bits, wherein the input logic identifies the random bits in the received control data packets to facilitate the creation of modified control data packets. The fluid ejection controller interface includes a clock signal generator to generate a second clock signal that is different than the first clock signal, and output logic to receive the modified control data packets, and output the modified control data packets to a fluid ejection controller of a fluid ejection device based on the second clock signal.

Abstract: An integrated circuit to drive a plurality of fluid actuation devices includes a plurality of first non-volatile memory cells and control logic. Each first non-volatile memory cell stores a customization bit. The control logic configures an operation of the integrated circuit based on the customization bits.
