    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, a punch out bit field, or a cryptographic command. The commands may be transmitted using a broadcast scheme or a split transaction scheme. 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.

    Abstract: A memory module, including a plurality of memory cells and a plurality of signal lines for communicating with a processing device. The memory module is configured such that following reception of a command and upon encountering a first condition while processing the command, the memory module limits a voltage on a first signal line of the plurality of signal lines to be no more than an intermediate voltage greater than voltage levels corresponding to a binary zero state and less than voltage levels corresponding to a binary one state for a period of time for indicating an occurrence of the first condition.

    Abstract: A method of operating a module is disclosed. The method includes determining if a voltage between a power connection and a ground connection exceeds a predetermined threshold and if so determined then setting a module communication address to a first address, responding to a first serial communication received via the serial communication connection addressed to the module communication address, and not responding to a second serial communication received via the serial communication connection addressed to a different address than the module communication address. Other methods and devices are disclosed.
