Wherein, the processing module may be, for example, an application processor.

As shown in FIG. 4, the power consumption management method of this embodiment may include the following steps 401 to 403:

Step 401. Obtain the memory usage of the storage module.

In this embodiment, when the user is using the application program in the electronic device, the memory of the storage module of the electronic device will be occupied during the use of the application program, and the application program currently running in the electronic device can be monitored through the processing module, and The memory usage of the storage module can be determined according to the currently running applications.

Wherein, the amount of memory occupied by each application program during running is preset.

For example, when the user is only using the application program A in the electronic device, and the memory usage of the application program A is A1, the memory usage of the storage module acquired by the processing module is A1.

For another example, when the user is using application program A and application program B in the electronic device, the memory usage of application program A is A1, and the memory usage of application program B is B1, then the processing module obtains the storage module of the memory The memory footprint of is A1+B1.

Step 402. Determine the working mode of the storage module according to the memory usage, wherein, when the memory usage is less than a preset memory usage, the working mode of the storage module is a low power consumption mode.

Wherein, when the memory usage of the storage module is less than the preset memory usage, the processing module determines to switch the storage module to a low power consumption mode; when the memory usage of the storage module is greater than or equal to the preset memory usage , the storage module remains in the normal working mode, and there is no need to switch the storage module to the low power consumption mode.

Wherein, the preset memory usage can be set by the developer of the electronic device, which is not specifically limited in this embodiment. For example, the preset memory usage may be 30%.

In this embodiment, it should be noted that the default working mode of the storage module is the normal working mode; wherein, in the normal working mode, all storage particles in the storage module are in an open state.

In this embodiment, in the low power consumption mode, some storage particles in the storage module are in the open state, and the rest of the storage particles are in the closed state. In the low power consumption mode, the power consumption of running the storage module can be reduced, extending the The battery life of electronic devices.

In this embodiment, when the storage module is in the low power consumption mode, if the memory usage of the storage module is greater than or equal to the preset memory usage, the storage module is switched to the normal working mode, the control switch module is turned on, All storage particles in all storage units are connected to the power module.

Step 403 , when the working mode of the storage module is a low power consumption mode, control the switch module to disconnect the target storage particle in the storage module from the power supply module.

In this embodiment, the execution subject of step 403 may be a processing module, or may be a controller in a memory.

In one embodiment, the power consumption management method of this embodiment may include the following step 501:

Step 501. When the working mode of the storage module is the normal working mode, control the switch module to conduct the connection between each storage particle in the storage module and the power supply module; When the memory usage is greater than or equal to the preset memory usage, the working mode of the storage module is the normal working mode. That is to say, in a normal working mode, all storage particles in the storage module are in an open state.

In one embodiment, step 403 specifically includes steps 4031 to 4033 .

Step 4031 , when the working mode of the storage module is the low power consumption mode, determine the storage particles in the K storage particle groups as target storage particles, K<M.

Step 4032, read the data in the target storage granule, and store the read data in the backup storage granule corresponding to the target storage granule, wherein the target storage granule and its corresponding backup storage granule correspond to the same The storage particle of the data channel, the backup storage particle is a non-target storage particle.

Step 4033: Control the switch module to disconnect the storage particles in the K storage particle groups from the power supply module.

Wherein, the data in the target storage granule can be directly read through the processing module, and the read data can be stored in the backup storage granule corresponding to the target storage granule, and the K storage granules can be disconnected by directly controlling the switch module through the processing module The connection between the storage particles in the group and the power module; the processing module can also send the data migration and backup instruction to the controller in the storage, and after the controller in the storage receives the data migration and backup instruction sent by the processing module, the The controller reads the data in the storage granule of the target storage granule, and migrates and backs up the read data to the backup storage granule corresponding to the target storage granule. After the data migration and backup in the target storage granule is completed, the processing module sends The controller in the memory sends a switch closing instruction corresponding to the target memory particle, and after the controller in the memory receives the switch closing instruction sent by the processing module, the controller in the memory controls the MOS switch corresponding to the target memory particle in the switch module to turn off. Disconnect to disconnect the target memory particle from the power module.

In one embodiment, in step 4031, when the number of storage particle groups is two, and the memory usage of the storage module is less than the preset memory usage, the processing module determines to switch the storage module to a low power consumption mode , the two storage particle groups are the first storage particle group and the second storage particle group, and the processing module determines the first storage particle group as the storage particle group that needs to be closed, then all the storage particles in the first storage particle group are closed It is determined as the target storage particle, wherein the memory usage of the first storage particle group is smaller than that of the second storage particle group.

In one embodiment, in step 4032, when all the storage particles of the first storage particle group are determined as the target storage particles, the data in all the target storage particles is read, and for each target storage particle, the target The data in the storage granule is migrated and backed up to its corresponding backup storage granule to realize the migration and backup of the data in the target storage granule; where, the backup storage granule is the remaining storage in the same storage unit except the target storage granule Particles, that is, non-target storage particles.

In one embodiment, in step 4033, after the data of all target storage particles are migrated and backed up to the corresponding backup storage particles, the MOS transistors corresponding to the target storage particles in the control switch module are turned off to disconnect the target storage particles. The particle is connected to the power module, thereby turning off the target storage particle and making the storage module enter a low power consumption mode.

In this embodiment, since the memory usage of the first storage particle group is smaller than the memory usage of the second storage particle group, all storage particles in the first storage particle group are determined as target storage particles, which facilitates fast and convenient By migrating and backing up the target storage granule to the backup storage granule, the amount of data is small, which can further reduce the energy consumption of the storage module.

For example, as shown in Figure 2, two storage particle groups (rank) are rank0 and rank1 respectively, and rank0 includes Die1, Die3, Die5 and Die7, and rank1 includes Die2, Die4, Die6 and Die8; 20%, and the memory usage of rank0 is less than that of rank1, and Die1, Die3, Die5 and Die7 in rank0 are all determined as the target storage particles, then Die2, Die4, Die6 and Die8 are all backup storage particles , read the data in Die1, Die3, Die5 and Die7, migrate and backup the data in Die1 to Die2, migrate and backup the data in Die3 to Die4, migrate and backup the data in Die5 to Die6, and transfer the data in Die7 to Die7 The data in Die1, Die3, Die5, and Die7 are migrated and backed up to Die8, and the data in Die1, Die3, Die5, and Die7 is migrated and backed up (that is, the memory usage of rank0 is 0), The first MOS tube and the third MOS tube in the control switch module are disconnected to disconnect Die1, Die3, Die5, and Die7 from the power module 101, and turn off Die1, Die3, Die5, and Die7, that is, turn off rank0, and only rank1 work and enter low power consumption mode.

In another embodiment, when there are multiple storage particle groups, a plurality of memory footprint ranges are preset according to the number of storage particle groups, wherein the number of memory footprint ranges is related to the number of storage particle groups Equal and one-to-one correspondence, multiple memory footprint ranges are continuous and do not overlap.

In another embodiment, when there are multiple storage particle groups, the smaller the boundary value of the memory footprint range where the memory footprint of the storage module is, the more storage particle groups need to be closed.

In another embodiment, after reading the data of the storage particle group that needs to be closed, the data of the storage particle group that needs to be closed can be migrated and backed up to any backup storage particle group.

For example, there are three storage particle groups (ranks) in the memory, the three storage particle groups (ranks) are rank2, rank3 and rank4 respectively, and the memory usage ranges from 0% to 30%, and from 30% to 50%. In the case of 50% to 100%, if the memory usage of the storage module is 0% to 30%, and the memory usage of rank3 is the largest, the data of all storage particles in rank2 and all storage particles in rank4 will be migrated Back up to all storage particles in rank3, and control the MOS transistors corresponding to all storage particles in rank2 and all storage particles in rank4 in the switch module to turn off; if the memory usage of the storage module is 30% ~50%, and the memory usage of rank2 is the smallest, migrate and back up the data of all storage particles in rank2 to all storage particles in rank3 and rank4, and control the MOS corresponding to all storage particles in rank2 in the switch module The tube is closed; if the memory usage of the storage module is 50%-100%, the storage module works in the normal working mode, and rank2, rank3 and rank4 all work normally.

In this embodiment of the present application, by controlling some of the MOS transistors in the switch module to disconnect the storage particles of some of the M storage particle groups from the power module, the memory enters the low power consumption mode of a single storage particle group or part of the The lower power consumption mode of the storage particle group reduces the available capacity of the memory. At the same time, because the storage particles of some storage particle groups are turned off, the power consumption of the power module is reduced, and the battery life of the electronic device is extended. In the case of less occupation, it will not affect the performance of electronic equipment.

In another embodiment, step 403 may be implemented by channel-by-channel differentiated control over the working states of the storage particles in the storage module. That is to say, when the working mode of the storage module is the low power consumption mode, the control switch module performs channel-by-channel control on the working states of the storage particles in the storage module according to the data channel, so that part of the data channels The corresponding storage particles are turned off, and the storage particles corresponding to some data channels are turned on, thereby reducing power consumption.

In another embodiment, step 403 specifically includes steps 4034 to 4036 .

Step 4034: When the working mode of the storage module is the low power consumption mode, determine the storage particles corresponding to the L data channels as target storage particles, where L<N.

Step 4035, read the data in the target storage granule, and store the read data in the backup storage granule corresponding to the target storage granule, wherein the target storage granule and its corresponding backup storage granule are the same A storage granule in a storage granule group, and a backup storage granule is a non-target storage granule.
