Abstract
Electrical interfaces, addressing schemes, and command protocols allow for communications with memory modules in computing devices such as imaging and printing devices. Memory modules may be assigned an address through a set of discrete voltages. One, multiple, or all of the memory modules may be addressed with a single command, which may be an increment counter command, a write command, or a punch out bit field. The status of the memory modules may be determined by sampling a single signal that may be at a low, high, or intermediate voltage level.
