Fragmentation management for memory systems

A method comprising:

• receiving, from a host, a file-based-optimization (FBO) entry comprising a plurality of logical block addresses (LBAs) associated with a file;
• accessing a page table that associates the plurality of LBAs with respective physical addresses of a set of memory components;
• determining a first quantity of read operations that need to be performed to read data from the physical addresses of the set of memory components associated with the plurality of LBAs;
• and
• determining a second quantity of LBAs representing how many LBAs are included among the plurality of LBAs;
• and
• computing a regression level for the file based on the first quantity of read operations that need to be performed to read data relative to the second quantity of LBAs that represent how many LBAs are included among the plurality of LBAs, the regression level computed as a ratio of the first quantity of read operations to a maximum number of read operations that need to be performed to read data associated with the plurality of LBAs.

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

• receiving, from a host, a file-based-optimization (FBO) entry comprising a plurality of logical block addresses (LBAs) associated with a file;
• accessing a page table that associates the plurality of LBAs with respective physical addresses of a set of memory components;
• determining a first quantity of read operations that need to be performed to read data from the physical addresses of the set of memory components associated with the plurality of LBAs;
• and
• determining a second quantity of LBAs representing how many LBAs are included among the plurality of LBAs;
• and
• computing a regression level for the file based on the first quantity of read operations that need to be performed to read data relative to the second quantity of LBAs that represent how many LBAs are included among the plurality of LBAs, the regression level computed as a ratio of the first quantity of read operations to a maximum number of read operations that need to be performed to read data associated with the plurality of LBAs.

A system comprising:

• a set of memory components of a memory sub-system;
• and
• a processing device operatively coupled to the set of memory components, the processing device being programmed to perform operations comprising:
• performing one or more data defragmentation operations based on comparing a regression level of a file to a threshold regression level;
• identifying a first set of physical addresses associated with a first set of a plurality of logical block addresses (LBAs) that corresponds to a same channel of the set of memory components as a second set of physical addresses associated with a second set of the plurality of LBAs, the first set of physical addresses corresponding to a first chip enable and the second set of physical addresses corresponding to a second chip enable on the same channel;
• and
• instructing the same channel of the set of memory components to interleave reading the second set of physical addresses based on the second chip enable with transferring data read from the first set of physical addresses to the processing device.

A system comprising:

• a set of memory components of a memory sub-system;
• and
• a processing device operatively coupled to the set of memory components, the processing device being programmed to perform operations comprising:
• determining a type of storage associated with one or more of physical addresses;
• transmitting, based on comparing a regression level of a file to a threshold regression level, a first regression indicator to a host system in response to determining that the type of storage associated with the one or more physical addresses is a first type;
• and
• transmitting, based on the comparing the regression level of the file to the threshold regression level, a second regression indicator to the host system in response to determining that the type of storage associated with the one or more physical addresses is a second type.
