Abstract
The present invention relates to utilizing memory provided in a machine replaceable sub-assembly to be one medium of distribution for software code updates to that machine relating as to how that machine should use that replaceable sub-assembly. In one embodiment, there is provided a replaceable sub-assembly for use in a machine at various setpoints including a memory and further including upgraded executable instruction suitable for directing the machine to use the replaceable sub-assembly with different setpoints, where the upgraded executable instruction is stored in the memory. In this way, the replaceable sub-assembly becomes the medium for it's own or another's software updates.
