1. A die for a printhead, comprising:
a configuration register;
a memory configuration register to operate parallel to the configuration register;
a plurality of fluidic actuator arrays;
a power line and a separate activation signal line routed across a feed zone of the die;
data blocks in a data store coupled to the memory configuration register, the data blocks comprising a data block associated with each of the plurality of fluidic actuator arrays; and
an interface comprising a data pad and a clock pad, wherein the data blocks are configured so that a data bit value present at the data pad is loaded into a first data block corresponding to a first fluidic actuator array on a rising clock edge and loaded into a second data block corresponding to a second fluidic actuator array on a falling clock edge.
