Consumable chip, consumable container and data writing method for the consumable chip

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.

Description

technical field [0001] The invention relates to the field of printing consumables, in particular to a consumable chip, a consumable container with the chip, and a data writing method for the consumable chip. Background technique [0002] As a common office equipment, printers provide great convenience for modern office. Existing printers are divided into inkjet printers and laser printers. Inkjet printers use ink cartridges containing ink as consumable containers to spray ink on paper to form text or patterns that need to be printed on paper; laser printers use ink cartridges containing toner The toner cartridge is used as a consumable container to form text or patterns that need to be printed on the medium. [0003] see figure 1 , an existing color inkjet printer has a casing 11, figure 1 The inkjet printer is shown with the chassis 11 omitted. The machine core 12 of ink-jet printer is provided with in the casing 11, and is provided with a slide bar, print word car 14 i...

AI Technical Summary

Problems solved by technology

[0015] However, as the communication speed between the inkjet printer or laser printer and the chip becomes faster and faster, the time required for data writing becomes shorter and shorter. Writing data after clearing will cause the data writing time to be too long, affect the communication speed between the chip and the printer, fail to meet the printing work requirements, and even cause the data sent by the printer to be unable to be written into the readable and writable storage area 35. If the phenomenon occurs, the printer will judge that the ink cartridge or toner cartridge is wrong and stop the printing operation

[0016] In order to solve the above problems, some existing chips use ferroelectric memory with a faster reading and writing speed to replace EEPROM or flash memory, but due to the high production cost of ferroelectric memory, the production cost of the chip is too high
