REPLACEABLE PRINTER COMPONENT INCLUDING A MEMORY UPDATED ATOMICALLY
摘要
<p>A replaceable printer component includes a memory device and a communication link. The memory device includes a memory and a circuit configured to atomically update data stored in the memory. The communication link is configured to communicatively link the memory device to a printer controller when the replaceable printer component is installed in a printing system. The circuit is configured to receive a write request including data, a data length, and an address from the printer controller; copy the data length of data stored at the address to a backup area of the memory; store the data length and the address in the memory; set a write state stored in the memory to a first state; update the data length of data stored at the address with the received data; and set the write state stored in the memory to a second state.</p>
