ADDRESSING, COMMAND PROTOCOL, AND ELECTRICAL INTERFACE FOR NON-VOLATILE MEMORIES UTILIZED IN RECORDING USAGE COUNTS |
摘要 |
<p>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.</p> |
