As shown in fig. 1, the present application provides a data processing method applied to a consumable chip, including the following steps:
copying an original main program in a nonvolatile memory unit into a copy main program according to a power-on signal, and transferring the copy main program to a volatile memory unit;
running the copy main program in the volatile storage unit, and detecting whether a write signal is received;
if yes, waking up the nonvolatile memory unit, and writing the write data corresponding to the write signal into the nonvolatile memory unit;
and if not, maintaining the dormant state of the nonvolatile memory unit.
In step S100, according to the power-on signal, the original main program in the nonvolatile memory unit is copied as a copy main program and transferred to the volatile memory unit;
the consumable chip may store an original program and original data, and may perform communication interaction with the image forming apparatus, specifically, information interaction actions including identity authentication of a printing consumable, printing state update of the printing consumable, remaining amount detection update of the printing consumable, and the like. The consumable chip carrying the original program and the original data comprises a nonvolatile memory and a volatile memory, so that the original main program and the original data of the consumable chip can be stored in the nonvolatile memory in order to ensure that the functions and important data of the consumable chip are not lost, and meanwhile, the data in the nonvolatile memory can be written or rewritten. In the present application, the nonvolatile memory unit is preferably configured as a Flash memory (Flash), and the volatile memory unit is preferably configured as a Static Random access memory (Static Random-AccessMemory, SRAM).
When the printing consumable is installed in the image forming device, the consumable chip arranged on the printing consumable can be electrically connected with the electrical contact in the image forming device, and after the door cover of the image forming device is closed, the image forming device is powered on, and the consumable chip starts to be powered on. After the consumable chip is powered on, the original main program in the nonvolatile memory is copied and stored in the volatile memory, wherein the original main program comprises an interaction main program of the consumable chip and the image forming device, an internal operation algorithm of the consumable chip and the like. In the process of copying and transferring the original main program, the nonvolatile memory and the volatile memory are in an upper working state, whether the original main program is completely transferred to the volatile memory or not is detected in real time, and after the copying and transferring of the original main program are detected, the power supply of the nonvolatile memory is disconnected, so that the nonvolatile memory is in a dormant state, and the power consumption of a chip is reduced. It can be understood that after or during the power-up process of the chip, the original main program in the nonvolatile memory is preferentially carried into the volatile memory, and the following program actions are executed, that is, the consumable chip is in a non-working state at this time. In order to ensure that the copy main program can normally run in the volatile memory, the data in the copy main program is required to be identical to the data in the original main program, so that the data sent to the volatile memory also comprises data such as a data length value, verification data and the like, when the copy main program is transported to the volatile memory, the data length value and the verification data of the copy main program are verified, and if the data length value and the verification data of the copy main program are verified to be correct, the transportation of the copy main program is confirmed to be completed; if the verification data length value and the verification data are wrong, the copy main program is considered to be failed to be conveyed, the original main program is copied again and conveyed until the copy main program is confirmed to be conveyed, and after the copy main program is confirmed to be conveyed, the power supply of the nonvolatile memory is disconnected, so that the nonvolatile memory is in a dormant state.
In step S200, the copy main program is run in the volatile storage unit, and whether a write signal is received is detected; if yes, waking up the nonvolatile memory unit, and writing the write data corresponding to the write signal into the nonvolatile memory unit; and if not, maintaining the dormant state of the nonvolatile memory unit.
After the main program is carried, the nonvolatile memory is in a dormant state, and the original main program in the nonvolatile memory cannot be operated after being electrified, so that the consumable chip can directly operate the copy main program in the volatile memory to communicate with the image forming device in order to ensure the normal communication between the consumable chip and the image forming device. However, data in the volatile memory is lost after power failure, so that when data writing or rewriting of the consumable chip is required, the data cannot be written into the volatile memory. In general, when data writing or rewriting is needed, a consumable chip will receive a write signal first and then write pre-written data into a predetermined address storage area, where the consumable chip detects whether the write signal is received and determines whether the data writing is needed to be performed on the consumable chip, and if the write signal is received, wakes up the nonvolatile memory unit and writes the write data into the nonvolatile memory unit; if the write signal is not received, the nonvolatile memory is kept in a dormant state, and the original main program in the nonvolatile memory does not run. In the operation process of the copying main program, the nonvolatile memory is kept in a dormant state, and only when data writing is needed to be carried out on the consumable chip, the consumable chip wakes up the nonvolatile memory to write corresponding writing data into the nonvolatile memory, so that the consumable chip can always keep low-power-consumption operation when the copying main program is operated, the power consumption of the consumable chip is greatly reduced, and the service life of the consumable chip is prolonged.
As shown in fig. 2, step S200 further includes:
in step S300, it is detected whether the writing of the write data is completed; if yes, the nonvolatile memory unit enters a dormant state.
After receiving the write signal, the consumable chip writes the write data into the nonvolatile memory according to the write signal, at this time, the nonvolatile memory is powered on, the overall power consumption of the consumable chip increases, multiple data writing actions may exist during the operation of the copy main program in the volatile memory, and the operation time of each writing action cannot be determined, so that after each data writing is completed, the nonvolatile memory needs to be put into a sleep state again. Specifically, in the process of writing data into the nonvolatile memory, whether the writing of the data is completed is detected in real time, if not, the data writing action is continued, and if the writing is completed, the nonvolatile memory unit is enabled to enter the dormant state again, so that the nonvolatile memory is enabled to be electrified only when the data is written into the nonvolatile memory, the overall power consumption of the consumable chip can be greatly reduced, and the service life of the chip is prolonged.
As shown in fig. 3, before step S200, the method further includes:
in step S400, the address of the volatile memory unit is set as a program start address.
When the consumable chip is operated, the initial address of the main program is used as the initial address of the operation of the chip, in the prior art, the main program is operated in the nonvolatile memory, so the initial address of the original main program is the program initial address of the chip.
As shown in fig. 4, on the basis of the data processing method applied to the consumable chip, the application further provides a consumable chip applied to a consumable box, wherein the consumable chip comprises: the device comprises a nonvolatile storage unit, a transfer unit, a volatile storage unit, a first detection unit and a control unit.

The consumable chip further includes a setting unit configured to set an address of the volatile memory unit as a program start address.
The consumable chip further comprises a second detection unit, wherein the second detection unit is configured to detect whether the writing of the write data is completed or not; the control unit is further configured to put the nonvolatile memory unit into a sleep state when the write data writing is completed.
