Quality of service for memory devices using suspend and resume of program and erase operations

A system comprising:

• a memory device;
• and
• a processing device, operatively coupled with the memory device, to:
• detect a first operation of a first input/output (I/O) operation type executing at a memory device;
• receive a request to execute a second operation of a second I/O operation type at the memory device;
• determine whether a percentage of execution time of the first operation satisfies a threshold condition;
• and
• responsive to determining that the percentage of execution time satisfies the threshold condition:
• continue to execute the first operation at the memory device;
• and
• responsive to determining that executing the first operation is complete, execute the second operation at the memory device.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:

• receive a request to execute a first operation of a first input/output (I/O) operation type at a memory device;
• determine whether a second operation of a second I/O operation type is being executed at the memory device;
• and
• responsive to determining that the second operation is being executed:
• cause the second operation to continue executing during a wait time period, wherein the wait time period is computed based on a predetermined time period modified to reflect a first operation weight of the first operation and a second operation weight of the second operation;
• and
• responsive to determining that the wait time period has elapsed:
• suspend the second operation execute the first operation at the memory device;
• and
• responsive to determining that executing the first operation is complete, resume execution of the second operation at the memory device.
