Detailed Description
The technical solution in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
The inventor of the present application has noticed that, in the conventional one-time programmable memory configuration, the number of times each Group memory cell 101 can be burned is fixed and unchangeable after being configured in advance. Fig. 1 is a configuration structure common in the prior art, as shown in fig. 1. Suppose that the memory is pre-configured with Y Group memory cells 101 capable of being burned; the Group1, the Group4, the Group7 and the Group8 are all pre-configured to be burned for 2 times; group3 represents an important and frequently changed register combination, so that one more recording times is reserved, and 3 recording times are configured in advance; group2, Group5, Group6, Group pm and Group y represent less used register combinations, and therefore, only one recordable time is reserved.
The above conventional method is characterized in that after pre-configuration, the method is fixed and not modifiable, thereby bringing about two defects: (1) taking the display Gamma as an example, assuming that the number of times of burning is 3, but if the production line of the module needs rework, the number of times of adjusting the display Gamma may exceed 3, but the module must be scrapped due to the limitation of the configuration of the one-time programmable memory, so that the module cannot be used; (2) the number of times that each Group memory cell 101 can be programmed in the otp memory is flexibly adjusted, but each programming still uses the Group as a unit, and if only a few data bits of the Group memory cell 101 are adjusted, the whole Group memory cell 101 still needs to be programmed.
Based on the above research, the present embodiment provides a data storage device 01, in which two storage spaces, i.e., a first storage space 10 and a second storage space 20, are designed for storing data; the first storage space 10 is pre-configured with a plurality of storage units 101 with fixed quantity, fixed size and fixed position as in the conventional manner, and is used for storing one-time programmable burning data; the second storage space 20 is used for storing the data to be changed in the first storage space 10; by storing the data in this way, after the one-time programmable burning data stored in the storage unit 101 is modified locally or wholly, the modification information is stored in the second storage space 20, and meanwhile, the number of times of modification is flexibly determined by the size of the second storage space 20, so that the two defects are avoided, the storage efficiency is improved, and the cost is saved.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a data storage device 01 according to an embodiment of the present application. The specific apparatus shown in fig. 2 will be described in detail below.
The data storage device 01 comprises a first storage space 10 and a second storage space 20, wherein the first storage space 10 comprises a plurality of storage units 101, and the storage units 101 are used for storing one-time programmable burning data; the second storage space 20 is used for storing changed data, and the changed data is used for indicating information of the one-time programmable burning data needing to be changed in the storage unit 101; the combination of the one-time programmable burning data and the alteration data is used to indicate the storage information of the data storage device 01.
The data storage device 01 may be an OTP (one time program) storage device, and may be another type of storage device. The data storage device 01 is designed with two storage spaces, and may include one or more storage spaces other than the first storage space 10 and the second storage space 20, and the positions and sizes of these storage spaces may be pre-configured according to actual needs.
The first storage space 10 includes a plurality of storage units 101 with different sizes, different burning times and different burning positions, and specifically, the storage units 101 may be respectively written into the first storage space 10 according to predefined arrangements and positions, and at the same time, one-time programmable burning data may be stored in the storage units 101 according to the above-mentioned conventional manner. Optionally, during burning, the IC type of the OLED display module is selected, whether to hook the OTP for continuation is configured, after hooking, the NG time elastic frame is adjusted, whether to continue the OTP burning is determined, the OTP burning is directly performed when the OK is adjusted, and the one-time programmable storage of the storage unit 101 is completed when the burning is completed.
The second storage space 20 has data information recorded therein that needs to be changed or modified in the first storage space 10. The position and size of the data information can be adjusted according to actual requirements and actual burning conditions, so that the burning times of the storage unit 101 in the first storage space 10 are not fixed any more, and the whole data information is not required to be burned again if local change is required; if the one-time programmable burning data stored in the storage unit 101 needs to be changed locally or wholly, the change-related information can be stored in the second storage space 20, and meanwhile, the number of times of change is flexibly determined by the size of the second storage space 20.
When the data storage device 01 works, firstly, the one-time programmable burning data stored in the first storage space 10 can be read in sequence, then the change data stored in the second storage space 20 can be read in sequence, after the change data is read, the data of the corresponding storage unit 101 in the first storage space 10 is updated, and the updated data is finally output data, so that the local or overall change of the one-time programmable burning data is realized, the burning times of the target data in each storage unit 101 are not fixed any more, the flexible burning of the target data is realized, and the space waste of the data storage device 01 is avoided.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a first storage space 10 according to an embodiment of the present disclosure. The first storage space 10 predefines the number, size, location and other basic properties of each storage unit 101, which respectively represent the basic characteristics of the storage units 101, such as the number of times that the storage units 101 can be burned, the storage capacity, and the burning physical location. Meanwhile, each memory cell 101 in the first memory space 10 has data bits with a fixed format, and specifically, may include three fixed data bits, namely, a recording flag data bit, a starting recording flag data bit, and a recording data bit.
In one embodiment, the first memory space 10 predefines the number of each of the memory cells 101, which is used to indicate the number of one-time programmable burning of the memory cells 101.
For example, the number of each memory unit 101 in the first memory space 10 is preset, and the number may represent the number of times that the memory unit 101 can be burned. Optionally, the first storage space 10 stores Y storage units 101 in Group form, which represents that the data storage device 01 can burn for Y times in total. As shown in fig. 3, the number of the memory cells 101 in which Group1 and Group4 are located is set to be 2, which means that the memory cells 101 in which Group1 and Group4 are located can be burned for 2 times; the number of the Group2, the Group5, the Group pM and the Group pY is set to be 1, which means that the storage units 101 where the Group2, the Group5, the Group pM and the Group pY are located can only be burned for 1 time; the number of the memory cells 101 in which Group3 is located is set to be 3, which means that the memory cells 101 in which Group1 and Group4 are located can be burned for 3 times.
In one embodiment, the first storage space 10 predefines the size of each of the storage units 101, and the size is used for indicating the size of the one-time programmable burning data in the storage unit 101.
Illustratively, the size of each storage unit 101 is preset in the first storage space 10, and the size may represent the size of the storage capacity of the storage unit 101, and may be one or more bytes. Alternatively, the first storage space 10 stores Y storage units 101 in the form of groups with different sizes, representing that the data storage device has 01 storage units 101 with different storage capacities. As shown in fig. 3, the storage cells 101 in which Group1, Group2, Group3, Group4, Group5 …, Group pm, and Group py are located have different lengths, that is, different storage capacities.
In one embodiment, the first storage space 10 predefines a burning position of each of the storage units 101, where the burning position is used to indicate an arrangement position of one-time programmable burning data in the storage unit 101.
Illustratively, the burning position of each storage unit 101 is preset in the first storage space 10, and the position may represent a physical arrangement position where the storage unit 101 stores data. Alternatively, the first storage space 10 stores Y storage units 101 with different sizes and locations in a Group format, and represents that the data storage device 01 storage units 101 have different storage capacity sizes and locations. As shown in fig. 3, the storage units 101 in which Group1, Group2, Group3, Group4, Group5 …, and the like are respectively located are sequentially arranged according to a predefined physical position.
In one embodiment, the memory unit 101 includes a burning identification data bit for indicating whether the one-time programmable burning data is burned or not.
For example, the burst cutting identification data bit in the memory unit 101 may be disposed at the head or the tail of the memory unit 101, and the burst cutting identification data bit may generally have two forms of values, i.e., "1" or "0". Wherein, the data bit value of the burning identification is "1", which represents that the state of the memory cell 101 is burnt; the bit value of the write flag is "0", which indicates that the state of the memory cell 101 is not yet written.
In one embodiment, the memory unit 101 includes a start-up programming flag bit, which is used to indicate whether the memory unit 101 is in a programming state.
For example, the start-up burst id data bit in the memory cell 101 may also be set at the head or the tail of the memory cell 101, and the start-up burst id data bit may generally have two types of values, i.e., "1" or "0". Wherein, the starting burning identification data bit value is '1', the burning switch of the memory unit 101 is turned on, and the memory unit 101 starts to burn the one-time programmable data; and starting the data bit value of the burning identification to be 0, closing the burning switch of the memory unit 101, and suspending the burning of the current one-time programmable data by the memory unit 101.
In one embodiment, the memory unit 101 includes a burst data bit for storing the one-time programmable burst data.
For example, the burning flag bit in the memory cell 101 may be set between the burning flag bit and the start burning flag bit, or may be set after or before the burning flag bit and the start burning flag bit. The burst data bits may store one-time programmable burst data in hexadecimal form, which includes one or more bytes of data in size.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a second storage space 20 according to an embodiment of the present disclosure.
In one embodiment, the change data includes a change data body and a change data header; the second storage space 20 includes a modified data body storage area and a modified data header storage area; the modified data body storage area is used for storing the one-time programmable burning data to be modified in the storage unit 101, and the modified data head storage area is used for indicating the one-time programmable burning data to be modified in the first storage space 10.
For example, the modified data stored in the second storage space 20 may specifically include a modified data body and a modified data head, and the two portions of data are respectively stored in the storage areas corresponding to the second storage space 20. The modified data header is mainly related to positioning information of the modified data body, and is used for indicating which part of data of which storage unit 101 in the first storage space 10 is modified by the modified data body; the changed Data body is the changed part of the Data content in the storage unit 101, such as the Data part shown in fig. 4.
Optionally, the IC further defines a OTP memory space, i.e. the second memory space 20, for storing the modified data information of the modified data body and the modified data header, and since only partial modification is generally performed, the reserved space of the second memory space 20 is much smaller than that of the first memory space 10, and about 1 kbyte can meet the requirement.
In one embodiment, the altered data header storage area comprises a first sub-storage area, a second sub-storage area and a third sub-storage area; the first sub-storage area is used for storing the name of the storage unit 101 where the changed data body is located; the second sub-storage area is used for storing the initial position of the storage unit 101 where the changed data body is located; the third sub-storage area is used for storing the number of changed bytes contained in the changed data body.
For example, the second storage space 20 may be provided with four storage areas for storing changed data. The first three storage areas, namely the first sub-storage area, the second sub-storage area and the third sub-storage area, may respectively store the name, the start position and the number of change bytes included in the storage unit 101 where the changed data body is located. As shown in fig. 4, the second storage space 20 continuously allocates N rows of storage areas for N changes, each row of storage area includes four storage areas, that is, a changed data header storage area and a changed data body storage area including a first sub storage area, a second sub storage area and a third sub storage area, and respectively stores changed data: group number (name of storage section 101), Address (start position), Word count (number of bytes changed included), and Data (Data after change).
In a preferred embodiment, the OLED display driving chip needs to perform Gamma correction on the image, the Gamma correction is to perform exponential transformation (i.e. Gamma transformation) on RGB data of the image, the cost is high for implementing the exponential transformation for the digital logic circuit, generally, output values of some fixed points (i.e. fixed input value points) in the RGB data are stored in a register in advance, and then linear interpolation is used to calculate output values between the fixed points when performing the Gamma correction.
Further, the fixed points corresponding to different Gamma transformations have different output values, and in order to meet different Gamma correction requirements, a plurality of storage units 101 with different numbers, sizes and positions may be disposed in the first storage space 10 for storing different output values of the preset fixed points. Alternatively, the first memory space 10 may be provided with Y Group memory cells 101, and the output value of each fixed point of the memory cells 101 is used for one kind of Gamma correction.
