Scheduling media management operations based on determined host system usage requirements
View Patent ↗A first time period during which the memory sub-system is expected to receive first host data from a host system and a second time period during which the memory sub-system is expected to receive second host data from the host system is determined in view of one or more prior programming operations performed at a memory sub-system. A memory management operation is scheduled to be performed between the first time period and the second time period.
1. A method comprising:
determining, in view of one or more prior programming operations performed at a memory sub-system, a first time period during which the memory sub-system is expected to later receive first host data from a host system and a second time period during which the memory sub-system is expected to later receive second host data from the host system; and
scheduling a memory management operation to be performed between the first time period and the second time period.
2. The method of claim 1 , wherein the memory management operation is scheduled based on a set of usage parameter values that correspond to at least one of a data burst rate, an amount of data write idle time, an average host system usage time, or a maximum host system usage time.
3. The method of claim 2 , wherein the set of usage parameter values is determined based on the performance of the one or more prior programming operations for a threshold amount of host data received from the host system and programmed to the memory sub-system.
4. The method of claim 1 , wherein scheduling the memory management operation to be performed between the first time period and the second time period comprises:
detecting that the first set of subsequent host data is stored at the memory sub-system;
performing the memory management operation at a first portion of memory devices of the memory sub-system; and
responsive to determining that the second set of subsequent host data is not to be received at the second time period, performing the memory management operation at a second portion of memory devices of the memory sub-system.
5. The method of claim 4 , further comprising:
responsive to determining that the second set of subsequent host data is to be received at the second time period, receiving the second set of subsequent host data at the second time period;
storing the second set of subsequent host data at the memory sub-system; and
performing the memory management operation at the second portion of memory devices of the memory sub-system.
6. The method of claim 4 , wherein determining that the second set of subsequent host data is not to be received from the host system at the second time period comprises:
transmitting a request, to the host system, inquiring whether the host system is to transmit the second set of subsequent host data at the second time period; and
receiving a response, from the host system, indicating that the second set of subsequent host data is not to be transmitted from the host system at the second time period.
7. The method of claim 1 , further comprising:
determining, based on the first time period and the second time period, an idle time period, wherein host data is not expected to be received from the host system during the idle time period; and
determining that the memory management operation is to be performed after the first set of subsequent host data is received at the first time period and during the idle time period.
8. The method of claim 1 , further comprising:
determining, a portion of memory devices of the memory sub-system to be reserved as a buffer space, wherein the buffer space is to store host data received from the host system while the memory management operation is being performed; and
reserving the determined portion of memory devices of the memory sub-system.
9. A system comprising:
one or more memory devices; and
a processing device, operatively coupled to each of the one or more memory devices, the processing device to perform operations comprising:
determining, in view of one or more prior programming operations performed at a memory sub-system, a first time period during which the memory sub-system is expected to later receive first host data from a host system and a second time period during which the memory sub-system is expected to later receive second host data from the host system; and
scheduling a memory management operation to be performed between the first time period and the second time period.
10. The system of claim 9 , wherein the memory management operation is scheduled based on a set of usage parameter values that correspond to at least one of a data burst rate, an amount of data write idle time, an average host system usage time, or a maximum host system usage time.
11. The system of claim 10 , wherein the set of usage parameter values is determined based on the performance of the one or more prior programming operations for a threshold amount of host data received from the host system and written at the one or more memory devices.
12. The system of claim 9 , wherein scheduling the memory management operation to be performed between the first time period and the second time period comprises:
detecting that the first set of subsequent host data is stored at the memory sub-system;
performing the memory management operation at a first portion of memory devices of the memory sub-system; and
responsive to determining that the second set of subsequent host data is not to be received at the second time period, performing the memory management operation at a second portion of memory devices of the memory sub-system.
13. The system of claim 12 , wherein the operations further comprise:
responsive to determining that the second set of subsequent host data is to be received at the second time period, receiving the second set of subsequent host data at the second time period;
storing the second set of subsequent host data at the memory sub-system; and
performing the memory management operation at the second portion of memory devices of the memory sub-system.
14. The system of claim 12 , wherein determining that the second set of subsequent host data is not to be received from the host system at the second time period comprises:
transmitting a request, to the host system, inquiring whether the host system is to transmit the second set of subsequent host data at the second time period; and
receiving a response, from the host system, indicating that the second set of subsequent host data is not to be transmitted from the host system at the second time period.
15. The system of claim 9 , wherein the operations further comprise:
determining, based on the first time period and the second time period, an idle time period, wherein host data is not expected to be received from the host system during the idle time period; and
determining that the memory management operation is to be performed after the first set of subsequent host data is received at the first time period and during the idle time period.
16. A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
determining, in view of one or more prior programming operations performed at a memory sub-system, a first time period during which the memory sub-system is expected to later receive first host data from a host system and a second time period during which the memory sub-system is expected to later receive second host data from the host system; and
scheduling a memory management operation to be performed between the first time period and the second time period.
17. The non-transitory computer-readable storage medium of claim 16 , wherein the memory management operation is scheduled based on a set of usage parameter values that correspond to at least one of a data burst rate, an amount of data write idle time, an average host system usage time, or a maximum host system usage time.
18. The non-transitory computer-readable storage medium of claim 17 , wherein the set of usage parameter values is determined based on the performance of the one or more prior programming operations for a threshold amount of host data received from the host system and programmed to the memory sub-system.
19. The non-transitory computer-readable storage medium of claim 16 , wherein to schedule the memory management operation to be performed between the first time period and the second time period, the processing device is to perform operations comprising:
