1. A fluid ejection device comprising:
a plurality of fluid actuation devices; and
an integrated circuit comprising:
a circuit configured to have a memory access state which can be set to one of an enabled state and disabled state, the circuit comprising 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 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;
a memory cell array, configured so that a memory cell in the memory cell array is accessible by the memory access state being set to the enabled state, and the data state bit being set; and
an analog bus having a single lane to simultaneously read a plurality of memory bits of the memory cell array over a same interface pad.
