9. A storage device to execute an adaptive flash interface module (FIM) protocol to optimize power consumption, the storage device comprising:
a memory device including sets of dies;
a set of FIMs, wherein each FIM connects a controller to a set of dies on the memory device; and
the controller, wherein the controller is configured to one of enable and disable a given number of FIMs according to an operating condition on the storage device,
wherein in a mode of operation the controller makes at least one FIM non-operational and triggers on a multiplexer to control a first FIM that is operational to communicate with a first set of dies connected to a second FIM that is non-operational and to also communicate with a second set of dies connected to the first FIM.
