Claim 0:
1. A print cartridge comprising a printhead die, the die comprising:
an ID line;
an array of fluid actuation devices;
a switch coupled with at least one of the fluid actuation devices;
a first latch coupled between the ID line and the switch to enable the switch in response to a first logic level on the ID line and disable the switch in response to a second logic level on the ID line;
a second latch having an input coupled with the ID line and an output coupled with a plurality of transistors; and
a fire line coupled with one or more of the fluid activation devices and the switch, the switch coupled between the fire line and a memory element, and the fire line to control activation of the at least one of the fluid activation devices in response to the first logic level on the ID line to enable the switch,
wherein the memory element is accessed through the fire line, responsive to the plurality of transistors receiving an address input when the ID line is at the first logic level.
