Abstract

The invention provides a consumable chip, a consumable container and a data writing method for the consumable chip. A base plate of the consumable chip is provided with an electronic module. A control unit and a memory allowing control unit accessing are arranged in the electronic module. A read-write data storage zone of the memory comprises at least one data storage block. The data storage block comprises more than two memory bytes and status flag bits corresponding to all the memory bytes, also comprises an address decoding circuit for searching the memory bytes according to the status flag bits, and also comprises an address modification circuit for modifying the status flag bits. The data writing method for the consumable chip comprises the following steps of receiving data by the electronic module, wherein the data needs to be written in the at least one data storage block, according to data stored in the status flag bits, searching a memory byte next to a memory byte in which data is written at last, and writing the received data in the searched memory byte. The data writing method for the consumable chip saves data writing time and realizes rapid communication between the consumable chip and a printer.
