Description

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

Technical Field

The invention relates to the technical field of printing consumables, in particular to a consumable chip, a data reading and writing method of the consumable chip and a consumable container applying the consumable chip.

Background

The electronic imaging equipment is taken as common office equipment, great convenience is provided for modern office, the common electronic imaging equipment comprises a printer, a copying machine and the like, the existing printer is divided into an ink-jet printer and a laser printer, and the ink-jet printer uses an ink box containing ink as a consumable container to jet the ink to paper so as to form characters or patterns to be printed on the paper; the laser printer uses a toner cartridge containing carbon powder as a consumable container to form characters or patterns to be printed on a medium.

Referring to fig. 1, a conventional color inkjet printer has a cabinet 11, and the inkjet printer shown in fig. 1 omits a tray of the cabinet 11. The housing 11 contains a movement 12 for an ink jet printer and a slide bar along which a carriage 14 reciprocates under the influence of a motor (not visible in fig. 1). A chip main control circuit board (not visible in fig. 1) is disposed in the carriage 14, and communicates with the movement 12 through a flat cable 13.

A plurality of ink cartridges 15 are detachably mounted on the carriage 14, and different ink cartridges 15 contain different color inks. The structure of the ink cartridge 15 is shown in fig. 2. The ink cartridge 15 has a cartridge body 16, the cartridge body 16 encloses a cavity for accommodating ink, an ink outlet 17 is provided at a lower end of the cavity, and the ink in the cavity flows out through the ink outlet 17 and supplies ink to an ink supply needle of the printing carriage 14.

A chip 18 is mounted on the outer wall of the casing 16 of the cartridge 15, the chip 18 having a substrate with a plurality of connection terminals 19 on one side for electrical connection with the contact pins on the carriage 14. The other side of the substrate is provided with a memory (not visible in fig. 2), which is usually a non-volatile memory, such as an EEPROM or a FLASH, and stores information related to the ink cartridge, including variable information and invariable information, where the variable information is information that is constantly changed with the printing operation, such as information about the remaining amount of ink, the printing duration, the number of printed sheets, and the invariable information is information that is not changed with the printing operation, such as the type of the ink cartridge, the type of an applicable inkjet printer, and the color of ink.

After the ink cartridge 15 is mounted to the carriage 14 of the ink jet printer, the ink jet printer powers up the chip 18 and reads the data stored in the memory of the chip 18 to determine whether the ink cartridge 15 is of the proper type, whether the amount of ink remaining in the ink cartridge 15 is sufficient, and the like. The ink jet printer can perform the printing operation only after the ink cartridge 15 is judged to be of a proper type and sufficient ink is present in the ink cartridge 15.

With the development of memory technology, some consumable chips have been embedded with ferroelectric memory. Because the ferroelectric memory utilizes the ferroelectric effect of the crystal, the state overturning can be completed in a very short time, compared with the traditional EEPROM which has longer erasing time, the read-write speed of the ferroelectric memory is very high, and the communication speed between the consumable chip and the printer can be improved.

If the ferroelectric memory is integrated in the integrated circuit module of the consumable chip, the production process requirements for the integrated circuit module are very high, and the production cost is also high, so that some consumable chips adopt other memories instead of the ferroelectric memory, for example, a random access memory (SRAM) is used instead of the ferroelectric memory. However, since the ram is a volatile memory, data will be lost after power failure, and therefore, a battery needs to be additionally added on the consumable chip, and when the inkjet printer does not supply power to the consumable chip, the battery supplies power to the ram so as to avoid data loss of the ram. However, since the battery has a large volume, the volume of the consumable chip is increased, and leakage and the like easily occur in the battery, which affects the safety of the use of the consumable chip.

Another conventional solution is to provide a random access memory and an EEPROM on a consumable chip, and the high-speed read-write frequency of the random access memory can meet the requirement of the inkjet printer for reading and writing data at a high speed, so that the consumable chip uses the random access memory to read and write data with the inkjet printer, and after the inkjet printer finishes reading and writing, the data in the random access memory is quickly transferred to the EEPROM, so that after the inkjet printer stops supplying power to the consumable chip, the data is stored in the EEPROM, thereby avoiding data loss.

However, when the random access memory writes data into the EEPROM, the data needs to be written back into the EEPROM row by row, but since the erase operation of the EEPROM requires a long time, the more data is written, the more electric energy needs to be consumed. In order to meet the requirement of power consumption when the random access memory writes data into the EEPROM, energy storage elements such as capacitors are often required to be arranged on the consumable chips. If the capacitance of the capacitor is too large, the normal power-on timing in the next communication is easily affected.

Another conventional consumable chip is disposed in an integrated circuit module of the chip and provided with a random access memory, and a ferroelectric memory is disposed outside the integrated circuit module, and the consumable chip communicates with an inkjet printer using the random access memory, and transfers data stored in the random access memory to the ferroelectric memory after the inkjet printer writes the data into the random access memory. However, the communication timing and communication speed between the inkjet printer and the ferroelectric memory are different from those between the inkjet printer and the random access memory, and this method is likely to cause data written into the random access memory to be erroneous, thereby affecting the operation of the inkjet printer.

Disclosure of Invention

The first purpose of the invention is to provide a consumable chip which has low production cost and small volume and effectively avoids data writing errors.

The second purpose of the invention is to provide a data reading and writing method of the consumable chip.

The second purpose of the invention is to provide a consumable container applying the consumable chip.

In order to achieve the first object of the invention, the consumable chip provided by the invention comprises a substrate, wherein an integrated circuit module is arranged on the substrate, and a controller and a random access memory are arranged in the integrated circuit module; the substrate is also provided with a ferroelectric memory which is arranged outside the integrated circuit module; the integrated circuit module is also provided with a first-in first-out memory, and the controller stores the target data written into the random access memory into the first-in first-out memory and writes the target data into the ferroelectric memory through the first-in first-out memory.

According to the scheme, the ferroelectric memory is arranged outside the integrated circuit module, so that the design cost of the integrated circuit module can be reduced. When the consumable chip is communicated with the ink-jet printer, the random access memory can be used as a main memory for data reading and writing, target data can be transferred to an external ferroelectric memory through the first-in first-out memory, the ferroelectric memory is used for maintaining data, and the problem of data loss after power failure is avoided.

In addition, because the first-in first-out memory is arranged to coordinate the data read-write data of the ink-jet printer, even if the speed of writing the data into the consumable chip by the ink-jet printer is high, the data is cached by the first-in first-out memory, and then the target data is transferred to the ferroelectric memory by the first-in first-out memory, so that the accuracy of the data written into the ferroelectric memory can be ensured, and the influence on the work of the ink-jet printer is avoided.

Preferably, the integrated circuit module is further provided with a serial communication interface, and the first-in first-out memory writes the target data into the ferroelectric memory through the serial communication interface.

Therefore, the target data can be ensured to be written into the ferroelectric memory according to the specified address through the serial communication interface, and the problem of data writing errors is avoided.

The further scheme is that the ferroelectric memory comprises a storage working area and a configuration area, wherein the storage working area is an encrypted memory, and the configuration area is a non-encrypted memory area.

Therefore, the configuration area can be used for storing data such as analog configuration, digital configuration, encryption configuration, redundant data and the like, the controller can directly read the data without decryption, and the data can be obtained, so that the data reading efficiency is improved. And aiming at the data needing to be kept secret, such as the operation logic and the like, the data are stored in the storage working area, so that the safety of the storage of the secret data, such as the operation logic and the like, is ensured.

In order to achieve the second objective, the method for reading and writing data of the consumable chip provided by the invention comprises the steps that the integrated circuit module of the consumable chip writes initial data in a ferroelectric memory arranged outside the integrated circuit module into a random access memory in the integrated circuit module; the target data written into the random access memory is acquired, the target data is written into a first-in first-out memory of the integrated circuit module, and the target data is written into the ferroelectric memory through the first-in first-out memory.

According to the scheme, the ferroelectric memory can store data such as consumable allowance when the power is off, therefore, after the consumable chip is powered on, initial data stored in the ferroelectric memory is written into the random access memory, and the ink-jet printer can directly read data from the random access memory. And when the ink-jet printer needs to write target data, the data can be written into the first-in first-out memory and then written into the ferroelectric memory by the first-in first-out memory, so that the communication speed between the ink-jet printer and the consumable chip is ensured.

In a preferred embodiment, after acquiring the target data to be written into the random access memory, the following steps are further performed: and judging whether the data quantity stored in the first-in first-out memory exceeds a preset threshold value, and if so, executing anti-overflow operation.

Therefore, once the FIFO memory stores more data and is about to overflow, the situation that the data of the FIFO memory overflows to cause data loss can be avoided by executing the anti-overflow operation.

Further, the anti-overflow operation comprises the following steps: the speed of writing data into the ferroelectric memory by the first-in first-out memory is increased, and preferably, the read-write frequency of the ferroelectric memory is increased.

Therefore, the speed of writing data into the ferroelectric memory is increased by increasing the read-write frequency of the ferroelectric memory, the target data can be written into the ferroelectric memory more quickly, and the data overflow of the first-in first-out memory can be effectively avoided.

Optionally, the anti-overflow operation includes: and writing the target data into a preset buffer area, and writing the data in the buffer area into the ferroelectric memory.

Therefore, the target data is firstly cached, and then the cached data is written into the ferroelectric memory, so that the condition that too much data is written into the first-in first-out memory in a short time can be avoided, and the data overflow of the first-in first-out memory can be effectively avoided.

Optionally, the anti-overflow operation includes: if the target data which is not written into the ferroelectric memory is rewritten again, the first-in first-out memory directly writes the rewritten data into the ferroelectric memory.

If the unwritten data is rewritten again, the unwritten and rewritten data is not written into the ferroelectric memory, so that the written data amount is reduced, the data required to be stored by the ferroelectric memory is reduced, and the condition of data overflow of the first-in first-out memory can be avoided.

Detailed Description

The consumable chip of the invention can be detachably arranged on a consumable container, and the consumable container of the invention can be an ink box arranged on an ink-jet printer or a toner box arranged on a laser printer. The following description will be given taking an ink cartridge mounted to an ink jet printer as an example.

Consumable chip embodiment:

referring to fig. 3, the integrated circuit module 20 is provided with an analog circuit 21, a digital control logic module 22 and a random access memory 31, wherein the analog circuit 21 and the digital control logic module 22 form a controller of the present embodiment for controlling reading and writing of data.

The consumable chip is further provided with a ferroelectric memory 32, in this embodiment, the ferroelectric memory 32 is disposed outside the integrated circuit module 20, but the ferroelectric memory 32 may be disposed on the substrate, and it is understood that the ferroelectric memory 32 and the integrated circuit module 20 are two different modules disposed on the same circuit board.

The integrated circuit module 20 is further provided with a communication interface 23, and the inkjet printer 40 performs data interaction with the analog circuit 21 through the communication interface 23, for example, issues an instruction to read data of the random access memory 31. Since the serial communication interface 24 is provided in the communication interface 23 and the integrated circuit module 20 performs data exchange with the ferroelectric memory 32 through the serial communication interface 24, data writing or reading to or from the ferroelectric memory 32 is performed in a serial manner.

The digital control logic module 22 is provided with a first-in first-out memory (FIFO)25 therein, and when data is written from the random access memory 31 to the ferroelectric memory 32, the written data is written into the ferroelectric memory 32 through the FIFO 25, that is, the data is first written into the FIFO 25, and then the data is written into the ferroelectric memory 32 through the FIFO 25.

Since the ferroelectric memory 32 is a nonvolatile memory, that is, data will not be lost after power failure, and the random access memory 31 is a volatile memory, that is, data will be lost after power failure, in this embodiment, the ferroelectric memory 32 is used for storing data, for example, data such as consumable surplus amount, in the power failure state of the consumable chip. Since the data read/write frequency of the random access memory 31 is very high, when the ink jet printer 40 reads and writes data, data exchange with the ink jet printer 40 is performed using the random access memory 31 as a main memory.

The ferroelectric memory 32 stores configuration data, operation logic and other data, and since the operation logic and other data are data that need to be kept secret, if the data that need to be kept secret are not encrypted, data leakage is easily caused to affect the safety of the operation of the consumable chip. For this purpose, the ferroelectric memory 32 is divided into two storage areas, see fig. 4, the ferroelectric memory 32 is divided into a storage working area 35 and a configuration area 36, wherein the storage working area 35 is used for running data that needs to be encrypted, such as logic, and therefore, the digital control logic module 22 needs to decrypt the data stored in the storage working area 35 through the decryption module 37, and when the digital control logic module 22 writes data into the storage working area 35, the data needs to be encrypted and then written through the encryption module 38. The encryption module 38 may encrypt the data written to the storage work area 35 using a known encryption algorithm, and accordingly, the decryption module 37 needs to decrypt the data of the storage work area 35 using a corresponding decryption algorithm.

Moreover, the target data to be written into the random access memory 31 is data that needs to be stored encrypted, and therefore the target data needs to be stored in the storage work area 35 after being encrypted by the encryption module 38. When the ferroelectric memory 32 sends data to the random access memory 31, the data needs to pass through the decryption module 37 before being output to the digital control logic module 22.

Referring to fig. 5, the configuration area 36 is used for configuration data such as analog configuration, digital configuration, encrypted configuration, and redundant data, and the configuration area 36 is a storage area that does not need to be encrypted, so that the digital control logic module 22 can directly read and write data in the configuration area 36 without performing encryption or decryption operations. Specifically, the configuration area 36 stores data including analog configuration (a bits in total for storing analog configuration related data), digital configuration (B bits in total for storing digital configuration related data), encryption configuration (C bits in total for storing a key for actually encrypting the storage work area), and redundant data (D bits in total for storing a random number). The data of the ferroelectric memory 32 can be written by burning, wherein in the data of the configuration area 36, the redundant data is actually a random number generated randomly, and the analog configuration is a configuration value adjusted according to the process, voltage and temperature deviation of the actual ferroelectric memory 32, and each ferroelectric memory may not be identical. The digital configuration is used to store the digital configuration and the encryption configuration of each ferroelectric memory 32 may be the same. As shown in fig. 5, the different configuration information is stored in different areas. Although the data of the encrypted configuration of each ferroelectric memory is the same, the safety of data storage can be increased by disordering the ordering of each data after the redundant random number, the analog configuration and the digital configuration are added. By increasing the number of bits of the redundant random number D, the data set of the configuration area 36 is arranged more out of order. After the data in the configuration area 36 is read in by the digital control logic module 22, the data in each area is identified and reordered to obtain the valid data in the configuration area 36. It can be seen that, in the embodiment, the data security of the configuration area 36 can be improved by increasing redundant data and increasing the difficulty of data decryption, particularly by increasing the difficulty of key data decryption in an out-of-order manner.

The embodiment of the data reading and writing method of the consumable chip comprises the following steps:

the data read/write method of the consumable chip is described with reference to fig. 6. Before the ink box is installed in the ink-jet printer for the first time, initial data of consumable chips, such as consumable allowance data, is written into the ferroelectric memory in a burning mode. When the consumable chip is powered on for the first time, step S1 is executed to write the data stored in the ferroelectric memory into the random access memory. For example, data of the ferroelectric memory is read into the random access memory through the serial communication interface. When the ink-jet printer reads data, the ink-jet printer sends the address of the data to be read to the controller, and the controller acquires corresponding data from the random access memory according to the address of the read data and sends the acquired data to the ink-jet printer.

Then, step S2 is executed to determine whether the inkjet printer issues an instruction to write target data. When the ink-jet printer needs to rewrite the data of the random access memory, the memory address of the target data needing to be rewritten and the specific numerical value of the target data are written into the consumable chip. If the ink jet printer does not write the target data to the consumable chip, it continues to wait. If the ink jet printer writes the target data to the consumable chip, the ink jet printer 40 writes the data to the random access memory 31 through the communication interface 23, and the random access memory 31 further executes step S3 to write the received target data to the ferroelectric memory 32.

Since the speed of writing the target data to the ram 31 by the ink jet printer 40 is different from the speed of writing the data to the ferroelectric memory 32 by the ink jet printer 40, if the target data is directly written from the ink jet printer 40 to the ferroelectric memory 32, the data writing may be inaccurate due to the excessively fast or excessively slow data writing/reading speed directly to the ferroelectric memory 32. Therefore, in the present embodiment, the consumable chip realizes writing of the target data from the random access memory 31 to the ferroelectric memory 32 through the first-in first-out memory 25. Specifically, step S4 is executed, and the digital control logic module 22 acquires the storage address of the target data written from the inkjet printer 40 to the random access memory 31, and sends the address of the target data and the corresponding data to the ferroelectric memory 32 through the serial communication interface 24 via the first-in first-out memory 25. The FIFO memory 25 can adjust the data writing speed according to the reading and writing speed of the ferroelectric memory 32, thereby avoiding the problem that data cannot be written accurately due to mismatching of reading and writing data.

Since writing a large amount of data into the fifo 25 in a short time easily causes data overflow of the fifo 25, the embodiment needs to perform an overflow prevention determination and an overflow prevention operation. Specifically, step S5 is executed to determine whether the amount of data stored in the fifo 25 exceeds a predetermined threshold, for example, the predetermined threshold is 80% of the capacity of the fifo 25, if not, step S7 is executed, and if the predetermined threshold is exceeded, it indicates that the fifo 25 is about to overflow, and step S6 is executed to prevent overflow.

Specifically, the anti-overflow operation can be performed in various ways: the first way is to increase the speed of writing data into the ferroelectric memory by the first-in first-out memory, for example, to increase the read/write frequency of the ferroelectric memory. Therefore, the ferroelectric memory can write data at a higher speed, can write a large amount of data into the ferroelectric memory as soon as possible, and can effectively avoid the problem of data overflow of the first-in first-out memory.

The second way is to write the target data into a preset buffer area and then write the data in the buffer area into the ferroelectric memory. For example, a buffer area is divided in the random access memory, and data to be written into the first-in first-out memory is stored in the buffer area in advance, so that a large amount of target data is prevented from being written into the first-in first-out memory in a short time.

In the third method, if the target data which has not been written into the ferroelectric memory is rewritten again, the first-in first-out memory directly writes the rewritten data into the ferroelectric memory. For example, if the ink jet printer 40 needs to continuously rewrite data at an address in the random access memory, the fifo memory should be written to the data at the address. In the anti-overflow operation, if the target data not written into the ferroelectric memory is rewritten again, the data before rewriting is not written into the ferroelectric memory, but the latest data is written into the ferroelectric memory directly, that is, the last received data is written directly, thereby reducing the amount of data required to be stored by the first-in first-out memory. Moreover, since the fifo also needs to include data heads each time data is written into the ferroelectric memory, the data heads actually occupy a certain storage space. The number of data writing into the ferroelectric memory is reduced, the number of data heads to be stored is also reduced, and the overflow of the FIFO memory is further effectively prevented.

Finally, step S7 is executed to determine whether the target data is completely written into the ferroelectric memory, and if not, the process returns to step S3 to continue writing the target data into the fifo 25 and writing the target data into the ferroelectric memory through the fifo.

Because the random access memory is arranged in the integrated circuit module, the requirement of high-speed data reading and writing of the ink-jet printer can be met because the data reading and writing speed of the random access memory is very high. In addition, the integrated ferroelectric memory is not arranged in the integrated circuit module, so that the production process difficulty of the integrated circuit module can be reduced, and the production cost of the consumable chip is reduced. In addition, in order to avoid the problem that data cannot be accurately written due to the fact that the data reading and writing speeds of the ink-jet printer to the random access memory and the ferroelectric memory are not consistent, the problem can be effectively solved by arranging the first-in first-out memory.

And, through ferroelectric memory storage target data, after the power failure of consumable chip, target data can not lose, when the next time of power on of consumable chip, can read the data of storage last time from ferroelectric memory, realize the high-speed communication between consumable chip and the inkjet printer under the circumstances such as not setting up battery or big electric capacity at the consumable chip.

Finally, it should be emphasized that the present invention is not limited to the above-mentioned embodiments, such as the change of the data stored in the configuration area of the ferroelectric memory, or the change of the internal structure of the consumable chip, and such changes should be included in the protection scope of the claims of the present invention.
