Management of program suspend and resume operations of a memory sub-system
A program operation is executed on a memory sub-system. During execution of the program operation, a request to execute a read operation on the memory sub-system is received. In response to receiving the request, a program suspend operation to suspend the program operation is executed. The read operation is executed on the memory sub-system in response to a completion of the program suspend operation. In response to completion of the read operation, a program resume operation is executed. A program suspend delay period is established following execution of the program resume operation during which a subsequent read operation is stored in a queue.
1. A method comprising:
executing, by a processing device, a program operation on a memory sub-system;
during execution of the program operation, receiving a request to execute a read operation on the memory sub-system;
in response to receiving the request to execute the read operation, executing a program suspend operation to suspend the program operation;
executing the read operation on the memory sub-system in response to a completion of the program suspend operation;
in response to a completion of the read operation, executing a program resume operation to resume the suspended program operation; and
establishing a program suspend delay period following execution of the program resume operation during which a subsequent read operation is stored in a queue to be executed following the program suspend delay period.
2. The method of claim 1 , further comprising:
in response to an expiration of the program suspend delay period, executing the subsequent read operation.
3. The method of claim 1 , wherein the read operation is associated with a multi-level cell (MLC) of the memory sub-system.
4. The method of claim 1 , further comprising recording a time of the executing of the program resume operation.
5. The method of claim 4 , wherein the program suspend delay period starts from the time of the executing of the program resume operation.
6. The method of claim 1 , further comprising:
maintaining a count corresponding to active read operations stored in the queue, wherein the executing of the program resume operation is further in response to determining that the count satisfies a threshold count value.
7. A system comprising:
a memory component; and
a processing device, operatively coupled with the memory component, to:
determine a program suspend delay period following execution of a program resume operation in response to receiving a first read operation associated with a memory sub-system;
during the program suspend delay period, receive a second read operation;
store the second read operation in a queue, the second read operation to be executed following the program suspend delay period; and
following an expiration of the program delay period, execute the second read operation that has been stored in the queue.
8. The system of claim 7 , wherein the processing device is further to:
maintain a count of active read operations in the queue;
determine that the count satisfies a threshold count value; and
issue a command corresponding to the program resume operation in response to determining that the count satisfies the threshold count value.
9. The system of claim 7 , wherein the processing device is further to:
execute a program operation on the memory sub-system; and
in response to receiving the first read operation, execute a program suspend operation to suspend the program operation.
10. The system of claim 9 , wherein the processing device is further to execute the first read operation following execution of the program suspend operation.
11. The system of claim 7 , wherein the processing device is further to:
maintain a first count corresponding to active read operations associated with the memory sub-system;
maintain a second count corresponding to active sequential read operations associated with the memory sub-system; and
in response to determining the first count satisfies a threshold count value and the second count satisfies the threshold count value, executing the program resume operation.
12. The system of claim 7 , wherein the processing device is further to execute a program suspend operation following expiration of the program suspend delay period.
13. The system of claim 12 , wherein the processing device is further to identify the first read operation is associated with a multi-level cell (MLC) of the memory sub-system.
14. The system of claim 7 , wherein the processing device is further to record a time of a start of the program resume operation, wherein the program suspend delay period starts from the time of the start of the program resume operation.
15. A non-transitory computer readable medium comprising instructions, which when executed by a processing device, cause the processing device to perform operations comprising:
executing, by the processing device, a program operation on a memory sub-system;
during execution of the program operation, receiving a request to execute a read operation on the memory sub-system;
in response to receiving the request to execute the read operation, executing a program suspend operation to suspend the program operation;
executing the read operation on the memory sub-system in response to a completion of the program suspend operation;
in response to a completion of the read operation, executing a program resume operation to resume the suspended program operation; and
establishing a program suspend delay period following execution of the program resume operation during which a subsequent read operation is stored in a queue to be executed following the program suspend delay period.
16. The non-transitory computer readable medium of claim 15 , the operations further comprising:
in response to an expiration of the program suspend delay period, executing the subsequent read operation.
17. The non-transitory computer readable medium of claim 15 , wherein the read operation is associated with a multi-level cell (MLC) of the memory sub-system.
18. The non-transitory computer readable medium of claim 15 , the operations further comprising:
recording a time of the executing of the program resume operation.
19. The non-transitory computer readable medium of claim 18 , wherein the program suspend delay period starts from the time of the executing of the program resume operation.
20. The non-transitory computer readable medium of claim 15 , the operations further comprising:
maintaining a count corresponding to active read operations stored in the queue; and
in response to determining the count satisfies a threshold count value, executing the program resume operation.
