Problems solved by technology

Since the data encryption level of the communication protocol used in the initial data programming is average, this makes it easy for the competitors of the recovery reset device manufacturer to crack the recovery reset principle and communication data through the recovery reset device, resulting in the recovery of the reset device of manufacturers suffered losses, which also adversely affected the security of data in memory chips

Embodiment 1

[0041] According to the use characteristics of the chip, the memory chip used in the imaging device can generally be divided into two regions, a rewritable region and a non-rewritable region. Among them, the data stored in the rewritable area is called variable data (such as the usage or remaining amount of the imaging material, etc.), and the data stored in the non-rewritable area is called immutable data (such as the imaging box model, the color of the imaging material in the imaging box, etc.) Wait).

[0042] The memory chip used in the imaging device needs to initialize the data in the chip before leaving the factory. The initialization of the memory chip is usually to use the burning equipment in the factory to write the initial data to the memory chip in batches and efficiently. This also requires that the burning device can change all the data in the memory chip, that is, the burning device can change both the variable data in the memory chip and the immutable data in ...

Embodiment 2

[0088] The type of the external controller connected to the memory chip is very important to the configuration of the data communication mode of the memory chip. This embodiment provides a memory chip for an imaging device that uses a port to determine the type of the external controller.

[0089] image 3 A schematic structural diagram of the memory chip provided by this embodiment is shown.

[0090] Such as image 3 As shown, the memory chip 300 provided in this embodiment includes a control module 102, a memory module 103, a first interface unit 301a, a second interface unit 301b, and a third interface unit 301c. Wherein, the first interface unit 301a, the second interface unit 301b and the third interface unit 301c are respectively connected with the factory programming device 302, the imaging device 303 and the recycling reset device 304. At the same time, the above three interface units are also connected to the control module 102 so as to transmit received signals to ...

Embodiment 3

[0097] Figure 4 A schematic structural diagram of another memory chip provided by this embodiment is shown. In addition to the interface module 101 , the control module 102 and the storage module 103 , the memory chip 300 is additionally provided with a first auxiliary interface 101 a and a second auxiliary interface 101 b. Wherein, the interface module 101 can be connected with the factory burning device 302 , the imaging device 303 or the recycling reset device 304 . When the factory programming device 302 is connected to the interface module 101, the factory programming device 302 is also connected to the first auxiliary interface 101a. When the recovery reset device 304 is connected to the interface module 101, the recovery reset device 304 is also connected to the second auxiliary interface 101b.

[0098] When the factory programming device 302 or the recovery reset device 304 reads and writes data to the memory chip 300 , it will send a mode start signal to the memory...

Abstract

The invention discloses a memory chip for imaging equipment. The memory chip comprises an interface module connected with an external controller and used for receiving a signal emitted by the external controller, a memory module for storing information related to an imaging box, and a control module connected between the interface module and the memory module and used for configuring the memory chip to a corresponding data communication mode according to the signal emitted by the external controller so as to realize data communication between the memory module and the external controller, wherein the control module can configure the data communication mode of the memory chip to a recovery resetting mode or a factory burning mode; and in the factory burning mode, the encryption degree of communication data is lower than the encryption degree of communication data in the recovery resetting, and the transmission speed and the transmission reliability of the data are higher than the transmission speed and the transmission reliability of the data in the recovery resetting. When recovery resetting is performed for the memory chip, the security of the communication data between the chip and the external controller is guaranteed.

Description

technical field [0001] The present invention relates to the field of imaging technology, in particular to a memory chip used for imaging equipment. Background technique [0002] Due to its high maintainability and easy use, detachable imaging cartridges (such as ink cartridges, powder cartridges, toner cartridges, etc.) have been widely used in different types of imaging equipment (such as inkjet printers, laser printers, etc.) , copier, etc.). [0003] In order to facilitate the management of the imaging box, the imaging device often needs to grasp the status information of the imaging box. For the ink cartridges used by inkjet printers, the status information of the ink cartridges that the inkjet printer needs to master includes immutable data such as the ink cartridge model, ink color, ink type, ink total amount, number of printed pages, ink remaining in the ink cartridge and other variable data. Therefore, the imaging box will be provided with a memory chip for storin...
