Read look ahead data size determination
A read request from a host system can be received. It can be detected that the read request is associated with a pattern of read requests. A requested transfer size associated with the read request can be identified. A size of data to retrieve can be determined. The size of the data can be based on the requested transfer size and a die-level transfer size associated with a die of a memory system.
1. A method comprising:
receiving a read request from a host system;
detecting that the read request is associated with a pattern of read requests;
identifying a requested transfer size associated with the read request;
determining, by a processing device, a size of data to retrieve that corresponds to a multi-plane operation on a memory system in response to detecting that the read request is associated with the pattern of read requests, the size of the data being based on the requested transfer size and a die-level transfer size utilizing a total number of planes comprised on a die of the memory system; and
providing an indication for the memory system to retrieve the data at the determined size.
2. The method of claim 1 , wherein:
the requested transfer size corresponds to an amount of data specified by the read request from the host system, and
the die-level transfer size corresponds to another amount of data associated with an architecture of the die.
3. The method of claim 2 , wherein the die-level transfer size is further based on a number of bytes that a page of each of the planes is capable of storing.
4. The method of claim 1 , wherein the data comprises:
a requested data based on the read request; and
additional data for subsequent read requests based on the pattern of read requests.
5. The method of claim 1 , wherein detecting that the read request is associated with the pattern of read requests comprises:
detecting that the read request is associated with a plurality of read requests for sequential logical block addresses (LBAs).
6. The method of claim 1 , wherein the size of the data is based on a larger size between the requested transfer size and the die-level transfer size.
7. A system comprising:
a memory system;
a processing device, operatively coupled with the memory system, to:
receive a read request from a host system;
detect that the read request is associated with a pattern of read requests;
identify a requested transfer size associated with the read request;
determine a size of data to retrieve that corresponds to a multi-plane operation on the memory system in response to detecting that the read request is associated with the pattern of read requests, the size of the data being based on the requested transfer size and a die-level transfer size utilizing a total number of planes comprised on a die of the memory system; and
provide an indication for the memory system to retrieve the data at the determined size.
8. The system of claim 7 , wherein:
the requested transfer size corresponds to an amount of data specified by the read request from the host system, and
the die-level transfer size corresponds to another amount of data associated with an architecture of the die.
9. The system of claim 8 , wherein the die-level transfer size is further based on a number of bytes that a page of each of the planes is capable of storing.
10. The system of claim 7 , wherein the data comprises:
a requested data based on the read request; and
additional data for subsequent read requests based on the pattern of read requests.
11. The system of claim 7 , wherein to detect that the read request is associated with the pattern of read requests, the processing device is to:
detect that the read request is associated with a plurality of read requests for sequential logical block addresses (LBAs).
12. The system of claim 7 , wherein the size of the data is based on a larger size between the requested transfer size and the die-level transfer size.
13. A non-transitory computer-readable medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
receiving a read request from a host system;
detecting that the read request is associated with a pattern of read requests;
identifying a requested transfer size associated with the read request;
determining a size of data to retrieve that corresponds to a multi-plane operation on a memory system in response to detecting that the read request is associated with the pattern of read requests, the size of the data being based on the requested transfer size and a die-level transfer size utilizing a total number of planes comprised on a die of the memory system; and
providing an indication for the memory system to retrieve the data at the determined size.
14. The non-transitory computer-readable medium of claim 13 , wherein:
the requested transfer size corresponds to an amount of data specified by the read request from the host system, and
the die-level transfer size corresponds to another amount of data associated with an architecture of the die.
15. The non-transitory computer-readable medium of claim 14 , wherein the die-level transfer size is further based on a number of bytes that a page of each of the planes is capable of storing.
16. The non-transitory computer-readable medium of claim 13 , wherein detecting that the read request is associated with the pattern of read requests comprises:
detecting that the read request is associated with a plurality of read requests for sequential logical block addresses (LBAs).
17. The non-transitory computer-readable medium of claim 13 , wherein the size of the data is based on a larger size between the requested transfer size and the die-level transfer size.
18. The method of claim 1 , wherein the multi-plane operation comprises:
performing at least one transfer of data operation on each plane of the total number of planes comprised on the die.
19. The system of claim 7 , wherein to perform the multi-plane operation, the processing device is to:
perform at least one transfer of data operation on each plane of the total number of planes comprised on the die.
20. The non-transitory computer-readable medium of claim 13 , wherein the multi-plane operation comprises:
performing at least one transfer of data operation on each plane of the total number of planes comprised on the die.
