Fig. 1 is a schematic flowchart of a device capacity configuration method in an embodiment of the present application, where an execution subject of the method may be a terminal device, and as shown in fig. 1, the device capacity configuration method may include the following steps:
step S101, detecting the storage blocks distributed on at least one pair of storage planes, and determining the distribution result.
When a bad Block exists on a certain storage plane (plane) of a storage product, a storage Block (Block) that needs to be used in pair with the bad Block at the relative position of another storage plane cannot be used, so in this embodiment, the storage blocks distributed on at least one pair of storage planes in the storage product need to be detected to determine the distribution result of each storage Block on each storage plane in the storage product, so that the terminal device can perform subsequent processing according to the distribution result on the storage planes. It will be appreciated that since the memory blocks on the memory planes are used in pairs, the number of individual memory blocks on at least one pair of memory planes in the memory product is uniform.
Optionally, as shown in fig. 2, step S101 includes:
step S201, detecting identification information of the storage blocks on the at least one pair of storage planes.
Step S202, determining the detection result of the storage block according to the identification information.
And S203, arranging the detection results in a preset sequence, and determining a distribution result.
In this embodiment, the identification information of the storage blocks on each storage plane in the storage product is detected by using a Flash algorithm, whether each storage block is normally usable or a bad block, that is, a detection result of the storage block, is determined according to the scanned presentation information, and then the detection results of the storage blocks are arranged according to a preset sequence, so as to determine a distribution result on the storage plane including each storage block, where the preset sequence may be a sequence in which the storage blocks are physically arranged on the storage plane.
And S102, determining the positions of the bad blocks on the at least one pair of storage planes according to the distribution result.
In this embodiment, the terminal device may determine the locations of the bad blocks on at least one pair of storage planes in the storage product according to the obtained distribution result, so that the locations that cannot be used on the current storage plane may be determined according to the locations of the bad blocks, so as to process the locations subsequently, and improve the capacity of the storage product.
Optionally, step S102 includes: constructing an initial mapping table according to the distribution result; determining a bad block location on the at least one pair of storage planes from the initial mapping table.
In this embodiment, an initial mapping table may be constructed according to the distribution result on the storage plane obtained through the above processing, as shown in fig. 3, and then the locations of the bad blocks on at least one pair of storage planes are determined by the initial mapping table, and the bad blocks are distinguished from the normally used storage blocks on the initial mapping table by different identifiers such as colors and characters, for example, as shown in fig. 3, taking Nand-Flash as an example, and the left column is the detection result of each Nand-Flash Block on the Nand-Flash plane0, and the total number is 10; the right column shows the detection results of the Nand-Flash blocks on the Nand-Flash plane1, the total number being 10. Wherein, P0_0003 and P0_0005 on the Nand-Flash plane0 are bad blocks; p1_0001, P1_0004 and P1_0007 on the Nand-Flash plane1 are bad blocks, and because the Nand-Flash memory product needs to execute a multiple plane operation based on performance considerations, that is, the Nand-Flash Block needs to be used in pairs, that is, the Nand-Flash plane0 and the Nand-Flash plane1 are used in combination, the number of the Nand-Flash Block pairs used in the memory product shown in FIG. 3 is 5, the usable ratio of the Nand-Flash Block pairs is only 50% of the Nand-Flash Block used, and the Nand-Flash Block usage rate is low.
Optionally, the initial mapping table may be displayed so as to be convenient for a relevant worker to observe.
Step S103, determining the state of the storage blocks on the opposite storage planes of the at least one pair of storage planes according to the positions of the bad blocks on the at least one pair of storage planes.
In this embodiment, the state of the storage block on the storage plane relative to the bad block is determined according to the determined positions of the bad blocks on at least one pair of storage planes, so as to determine whether the state of the storage block used in pair with the bad block is capable of being used normally or a bad block, so that the storage block which cannot be used normally due to the existence of the bad block is processed subsequently, and the storage block is reused.
Optionally, step S103 includes:
determining the state of the storage block at the relative position of the second storage plane from the distribution result according to the position of the bad block on the first storage plane;
and determining the state of the storage block at the relative position of the first storage plane from the distribution result according to the position of the bad block on the second storage plane.
In this embodiment, the pair of storage planes includes a first storage plane and a second storage plane, and the state of the storage block at the relative position of the second storage plane is determined from the obtained distribution result according to the location of the bad block on the first storage plane, or the state of the storage block at the relative position of the first storage plane is determined from the obtained distribution result according to the location of the bad block on the second storage plane. For example, the states of P1_0003 and P1_0005 on the corresponding Nand-Flash plane1 are determined according to the bad block distribution position of the Nand-Flash plane0 in FIG. 3, and it can be seen that both P1_0003 and P1_0005 can be used normally; the states of P0_0001, P0_0004 and P0_0007 on the corresponding Nand-Flash plane0 are determined according to the bad block distribution position of the Nand-Flash plane1, and P0_0001, P0_0004 and P0_0007 can be normally used as can be seen in the figure.
And step S104, carrying out pairing on the storage blocks on the opposite storage planes again according to the states of the storage blocks on the opposite storage planes by using a preset rule.
In this embodiment, the memory blocks on the opposite storage plane are re-paired according to the determined state of the memory blocks on the opposite storage plane according to a preset rule, that is, if the memory blocks on the opposite storage plane can be normally used, the memory blocks can be re-paired, so that the memory blocks which cannot be used due to the existence of the bad blocks can be re-used, thereby increasing the capacity of the memory and further achieving the purpose of increasing the yield of mass production of memory products. It is to be understood that if the memory block on the opposite memory plane is also a bad block, which indicates that the memory block on the opposite memory plane is also a memory block that cannot be used, the recoupling is not performed.
By way of specific example and not limitation, as can be seen from fig. 4 after the storage product is subjected to the re-pairing based on the bad Block distribution condition in fig. 3, the re-pairing of P0_0001, P0_0004 and P0_0007 on the Nand-Flash plane0 and the re-pairing of P1_0003 and P1_0005 on the Nand-Flash plane1 can promote the number of paired use of the Nand-Flash blocks of the storage product to be increased to 7, so that the usable ratio of the Nand-Flash blocks is only increased to 70%, the capacity of the storage product is greatly increased, and the yield of mass production is increased.
Optionally, the preset rule may be set according to a user requirement, for example, random pairing may be performed, pairing may be performed according to a physical arrangement distance of the storage blocks, or pairing may be performed based on other factors, which is not limited herein.
Optionally, correspondingly, step S104 includes:
and when the states of the storage blocks at the relative positions of the first storage plane and the second storage plane are both normal states, pairing the storage blocks at the relative positions of the first storage plane and the second storage plane according to a preset rule.
Optionally, after step S104, the method includes:
constructing a pairing table according to the pairing state of the newly paired storage blocks; and when receiving the use request, controlling the re-paired storage blocks to perform corresponding operation according to the pairing table.
In this embodiment, the terminal device constructs the pairing table according to the pairing state of the newly paired storage blocks, as shown in fig. 4, when receiving the usage request, the terminal device may randomly select the storage blocks paired with each other according to the pairing table to perform the corresponding operation according to the usage request, for example, when a group of data needs to be stored in the storage block pair, the terminal device may randomly select or select in a set order, determine the storage block pair in which the data is to be stored, and control the storage block pair to perform the storage operation.
In the embodiment of the application, storage blocks distributed on at least one pair of storage planes are detected, and a distribution result is determined; the bad block positions on the at least one pair of storage planes are determined according to the distribution result, so that how many bad blocks on each current storage plane can be determined, the storage blocks need to be used in pairs, the state of the storage block on the opposite storage plane of the at least one pair of storage planes is determined according to the bad block positions on the at least one pair of storage planes, the state of the storage block on the other storage plane used in pairs with the bad blocks can be obtained, and the storage blocks on the opposite storage planes are re-paired according to the state of the storage blocks on the opposite storage planes according to a preset rule, so that the storage blocks which cannot be used due to the bad blocks are re-paired, the utilization rate of the storage blocks is improved to the maximum extent, the capacity of storage products is improved, and the yield of the mass production of the storage products is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
