With the popularization of electronic devices, electronic devices are indispensable in the lives of people. In general, a storage medium in the electronic device is a Flash memory (Flash memory) in a nonvolatile memory, and a user can store data such as a photograph, a document, and personal information by using the Flash memory in the electronic device.
With the increasing demand for storage capacity, a single flash memory block can store more and more data bits. However, the time for the flash memory block to store data is shortened due to the fact that the number of data bits stored in the flash memory block is increased, and if the data stored in the flash memory block is not refreshed in time, the data can be lost or damaged, and hidden danger and inconvenience of data loss are brought to users. In the prior art, a passively triggered refresh mechanism is generally adopted to refresh the data stored in the flash memory block. That is, the controller of the electronic device determines whether the data stored in each flash memory block needs to be refreshed according to the state of the flash memory block, the wear-out state of the flash memory block, and the preset refresh algorithm, and refreshes the data stored in a certain flash memory block when it is determined that the data stored in the flash memory block needs to be refreshed.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion. Further, in the description of the embodiments of the present invention, "a plurality" means two or more unless otherwise specified.
The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone.
The terminal equipment in the embodiment of the invention can be intelligent peripheral equipment, mobile terminal equipment or non-mobile terminal equipment. The mobile terminal device may be a terminal device, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, a usb disk, or a Personal Digital Assistant (PDA), etc.; the non-mobile terminal device may be a Personal Computer (PC), a Television (TV), a teller machine, a self-service machine, or the like, and the embodiment of the present invention is not particularly limited.
The embodiment of the invention provides a flash memory data refreshing method, and an execution main body of the flash memory data refreshing method can be any one of the terminal equipment. Specifically, referring to fig. 1, the flash data refresh method includes the following steps S101 to S104:
s101, acquiring the data storage time length of each flash memory block of the terminal equipment.
The data storage time length of the flash memory block in the embodiment of the invention refers to the time length from the current time to the time of storing data into the flash memory block or the time length from the current time to the time of refreshing the data stored in the flash memory block last time. If the data stored in the flash memory block is not refreshed after being stored in the flash memory block, the data storage time length of the flash memory block is the time length from the current time to the time of storing the data in the flash memory block, and if the data stored in the flash memory block is refreshed after being stored in the flash memory block, the data storage time length of the flash memory block is the time length from the current time to the last time of refreshing the data stored in the flash memory block.
Specifically, the timer corresponding to the flash memory block may be started when data is stored in the flash memory block, and the timer is cleared after the data stored in the flash memory block is refreshed, and when the data storage time length of a certain flash memory block needs to be obtained, the data storage time length of the flash memory block may be obtained by reading the value of the corresponding timer.
S102, judging whether a flash memory block to be refreshed exists or not.
And the flash memory block to be refreshed is a flash memory block with the data storage time length being greater than the threshold time length.
That is, it is determined whether there is a flash block whose data storage time length is greater than a threshold time length.
For example, a timer may be set for each flash block, the timer is started when the input is stored in the flash block, the timer is cleared after the data in the flash block is refreshed, and whether the flash block to be refreshed exists is determined by determining whether the timer has timed out.
It should be noted that, in the embodiment of the present invention, all flash memory blocks may be the same type of flash memory block, for example: all three-Level (TLC) flash memory blocks, or all four-Level (Quad Level Cell, QLC) flash memory blocks, or all Single-Level (SLC) flash memory blocks, or all Multi-Level (MLC) flash memory blocks. When all flash memory blocks may be the same type of flash memory block, the threshold time lengths corresponding to all flash memory blocks may be the same. The terminal device may also include flash blocks of the same type, for example: when the terminal equipment comprises the flash memory blocks of the same type, the threshold time lengths corresponding to the flash memory blocks of the same type are the same, and the threshold time lengths corresponding to the flash memory blocks of different types are different.
Optionally, the threshold time length is a product of a theoretical reliable storage time length of each flash memory block and a preset value;
the preset value is greater than 0 and less than or equal to 1.
For example, when the flash block to be refreshed is a TLC flash block, the theoretical reliable storage time of the TLC flash block is 5 years, and the preset value is 70%, the threshold time length may be 5 × 70% — 3.5 years.
For example, when the flash memory block to be refreshed is a QLC flash memory block, the theoretical reliable storage time length of the TLC flash memory block is 3 years, and the preset value is 90%, the threshold time length may be 3 × 90% — 2.7 years.
In the step S102, if it is determined that there is a flash block to be refreshed, the following step S103 is executed, and if it is determined that there is no flash block to be refreshed, the flash data refreshing method provided in the embodiment of the present invention is ended, and it is determined again whether there is a flash block to be refreshed after a preset time length.
S103, judging whether the state of the terminal equipment meets a preset condition or not.
Namely, the current state of the terminal equipment is obtained, and whether the current state of the terminal equipment is suitable for refreshing the data stored in the flash memory block to be refreshed or not is judged.
For example, after it is determined that there is a flash memory block to be refreshed, the state of the terminal device may be detected in real time to determine whether the state of the terminal device meets a preset condition.
In the step S103, if it is determined that the state of the terminal device satisfies the preset condition, the following step S104 is executed, and if it is determined that the state of the terminal device does not satisfy the preset condition, the state of the terminal device continues to be detected.
And S104, refreshing the data stored in the flash memory block to be refreshed.
Specifically, the refreshing the data stored in the flash memory block to be refreshed includes: firstly, reading the data stored in the flash memory block to be refreshed, then deleting the data stored in the flash memory block to be refreshed, and finally rewriting the read data into the flash memory block to be refreshed.
As an optional implementation manner of the embodiment of the present invention, the method further includes:
and marking the flash memory block to be refreshed through the target identification under the condition that the flash memory block to be refreshed exists.
If it is determined that the flash memory block to be refreshed exists, the flash memory block to be refreshed is marked by the target identifier, then step S104 (refreshing the data stored in the flash memory block to be refreshed when it is determined that the state of the terminal device satisfies the preset condition) may be:
and under the condition that the state of the terminal equipment is determined to meet the preset condition, refreshing the data stored in the flash memory block with the target identifier, and deleting the target identifier after the refreshing is finished.
The flash memory blocks to be refreshed are marked through the target identification, so that the flash memory blocks to be refreshed can be quickly determined when the data stored in the flash memory blocks to be refreshed are refreshed, and the refreshing efficiency of the flash memory blocks to be refreshed is further improved.
The flash memory data refreshing method provided by the embodiment of the invention firstly obtains the data storage time length of each flash memory block of the terminal equipment, then judges whether the flash memory block to be refreshed exists, the data storage time length of which is greater than the threshold time length, judges whether the state of the terminal equipment meets the preset condition if the flash memory block to be refreshed exists, and refreshes the data stored in the flash memory block to be refreshed under the condition that the state of the terminal equipment meets the preset condition. Compared with the prior art that a passively triggered refresh mechanism is adopted to refresh the data stored in the flash memory blocks, the flash memory data refresh method provided by the embodiment of the invention can refresh the data stored in the flash memory blocks to be refreshed, the data storage time length of which is greater than the threshold time length, based on the data storage time length of each flash memory block and the state of the terminal equipment.
As an optional implementation manner of the embodiment of the present invention, referring to fig. 2, the step S103 (determining whether the state of the terminal device satisfies a preset condition) includes:
s201, judging whether the terminal equipment is in a charging state.
Illustratively, the terminal device can be determined whether to be in a charging state by information interaction with the power management module, or the terminal device can be determined whether to be in a charging state by reading the battery voltage and determining whether to be in a charging state according to the battery voltage.
In the step S201, if it is determined that the terminal device is in the charging state, it is determined that the state of the terminal device satisfies the preset condition, and step S104 is executed; and if the terminal equipment is determined to be in the non-charging state, determining that the state of the terminal equipment does not meet the preset condition, and continuously monitoring whether the terminal equipment enters the charging state.
Because a large amount of electric energy of the terminal device is consumed for refreshing the data in the flash memory block, if the data in the flash memory block is refreshed in a non-charging state, the power supply of the terminal device is very likely to be exhausted, and the terminal device is further shut down. The embodiment refreshes the data stored in the flash memory block to be refreshed only when the terminal device is determined to be in the charging state, so that the embodiment can avoid the power supply exhaustion of the terminal device caused by the refreshing of the data in the flash memory block.
As an optional implementation manner of the embodiment of the present invention, referring to fig. 3, the step S103 (determining whether the state of the terminal device satisfies a preset condition) includes:
s301, judging whether the terminal equipment is in a standby state.
Specifically, whether the terminal device is in the standby state can be judged by detecting whether the terminal device has the user input. The user input may be touch input, voice input, peripheral input, a specific gesture, and the like.
In the step S301, if it is determined that the terminal device is in the standby state, it is determined that the state of the terminal device satisfies the preset condition, and step S104 is executed; and if the terminal equipment is determined to be in the non-standby state, determining that the state of the terminal equipment does not meet the preset condition, and continuously monitoring whether the terminal equipment enters the standby state.
Because resources such as a memory and a processor of the terminal device are occupied by refreshing the data in the flash memory block, if the data in the flash memory block is refreshed when the user operates the terminal device, the performance of the terminal device may be affected by occupying too many resources of the terminal device. The embodiment refreshes the data stored in the flash memory block to be refreshed only when the terminal device is determined to be in the standby state, so that the embodiment can avoid performance degradation of the terminal device caused by refreshing the data in the flash memory block.
As an optional implementation manner of the embodiment of the present invention, referring to fig. 4, the step S103 (determining whether the state of the terminal device satisfies a preset condition) includes:
s401, judging whether the terminal equipment is in a charging state.
S402, judging whether the terminal equipment is in a standby state.
In the above steps S401 and S402, if it is determined that the terminal device is in the charging state and it is determined that the terminal device is in the standby state, it is determined that the state of the terminal device satisfies the preset condition, and step S104 is executed; and if the terminal equipment is determined to be in a non-charging state and/or the terminal equipment is determined to be in a non-standby state, determining that the state of the terminal equipment does not meet the preset condition, and continuously monitoring whether the terminal equipment meets the preset condition.
The embodiment refreshes the data stored in the flash memory block to be refreshed only when the terminal equipment is determined to be in the charging state and the standby state, so that the embodiment can not only avoid the power supply exhaustion of the terminal equipment caused by the data in the flash memory block being refreshed, but also avoid the performance reduction of the terminal equipment caused by the data in the flash memory block being refreshed.
As an alternative implementation manner of the embodiment of the present invention, referring to fig. 5, the step S104 (refreshing the data stored in the flash memory block to be refreshed) includes:
s501, obtaining the time length of the expiration of each flash memory block to be refreshed.
The time length of the expiration of any flash block to be refreshed is the difference value between the data storage time length of the flash block and the threshold time length.
Illustratively, the data storage time length of a certain flash block to be refreshed is T1, and the threshold time length is T2, then the expiration time length of the flash block to be refreshed is T1-T2.
And S502, sorting the flash memory blocks to be refreshed in a descending order according to the time length of the expiration.
That is, for a flash block to be refreshed, the longer the expiration time length is, the earlier the partial order of the flash block to be refreshed in the sorting result is.
S503, refreshing the data stored in the flash memory block to be refreshed according to the descending sorting result.
For a flash block to be refreshed, the longer the timeout period, the greater the risk of data corruption or loss. In the embodiment, the expiration time length of each flash memory block to be refreshed is obtained first, the flash memory blocks to be refreshed are sorted in a descending order according to the expiration time length, and the data stored in the flash memory blocks to be refreshed are refreshed according to the sorting result in the descending order under the condition that the state of the terminal device is determined to meet the preset condition.
Based on the same inventive concept, as an implementation of the foregoing method, an embodiment of the present invention further provides a flash memory data refresh device for executing the flash memory data refresh method provided in the foregoing method embodiment, where this embodiment corresponds to the foregoing method embodiment, and for convenience of reading, details in the foregoing method embodiment are not repeated one by one in this embodiment, but it should be clear that the flash memory data refresh device in this embodiment can correspondingly implement all the contents in the foregoing method embodiment.
