Consumable chip, data writing method thereof and consumable container of consumable chip

Abstract

The invention provides a consumable chip, a data writing method of the consumable chip and a consumable container of the consumable chip. An interface unit, a control unit and a nonvolatile memory are arranged on an electronic module of the chip. The nonvolatile memory is divided into more than two pages of memory intervals, wherein each page of memory intervals are provided with a plurality of memory bytes. A read-write control circuit is arranged inside the control unit, and is provided with an address coding module which is used for receiving address information and coding the address information to form memory byte address information in one page of memory intervals. A data latching device provided with a plurality of data registers is provided with a plurality of state register groups of state registers, wherein the number of the state register groups is equal to the number of the data registers. The control unit is provided with a read-write controller for receiving data needing to be written into the nonvolatile memory and for writing the received data into the data registers. According to the data writing method, the received data is written into the data latching device, and after all data is received, the received data is written into the nonvolatile memory. By means of the data writing method, read-in data speed of the nonvolatile memory of the consumable chip can be improved.

Description

technical field [0001] The invention relates to the field of printing, in particular to a consumable chip mounted on a printing consumable, a data writing method for the chip, and a consumable container equipped with 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 ...

For the same reason, the chip 33 will also have a long time to write data to the EEPROM, resulting in data loss.

[0013] In addition, toner cartridges or toner cartridges can be detachably installed on most existing imaging equipment such as copiers, fax machines, or all-in
