Handling operation collisions in a non-volatile memory

1. A method comprising:

assigning a first operation identifier to a current operation directed to a memory component, the first operation identifier having a first entry in a first data structure that associates the first operation identifier with a first buffer identifier;

determining whether the current operation collides with a prior operation assigned a second operation identifier, the second operation identifier having a second entry in the first data structure that associates the second operation identifier with a second buffer identifier;

determining whether the current operation is a read or a write operation; and

updating, in response to determining that the current operation collides with the prior operation and that the current operation is a write operation, a latest flag to indicate that the second entry is no longer the latest of multiple operations directed to an address.

2. The method of claim 1 , wherein the determining whether the current operation collides with the prior operation comprises checking a second data structure for an entry that has an address that matches the address to which the current operation is directed.

3. The method of claim 1 , further comprising incrementing a counter associated with the first buffer identifier.

4. The method of claim 1 , wherein the first data structure is stored in a memory outside of the memory component.

5. The method of claim 1 , further comprising:

assigning a third operation identifier to a subsequent operation directed to a memory component, the third operation identifier having an entry in the first data structure that associates the third operation identifier with a plurality of buffer identifiers; and

updating, in response to determining that the subsequent operation collides with the current operation and that the subsequent operation is a read operation, the plurality of buffer identifiers to include a buffer identifier associated with the current operation.

6. The method of claim 5 , wherein the updating comprises replacing a buffer identifier included in the plurality of buffer identifiers with the buffer identifier associated with the current operation.

7. The method of claim 5 , further comprising:

determining that the prior operation is a read operation; and

updating, in response to determining that the subsequent operation collides with the prior operation and that the prior operation is a read operation, the entry in the first data structure associated with the second operation identifier to identify the third operation identifier.

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

assign a first operation identifier to a current operation directed to a memory component, the first operation identifier having a first entry in a first data structure that associates the first operation identifier with a first buffer identifier;

determine whether the current operation collides with a prior operation assigned a second operation identifier, the second operation identifier having a second entry in the first data structure that associates the second operation identifier with a second buffer identifier;

determine whether the current operation is a read or a write operation; and

update, in response to determining that the current operation collides with the prior operation and that the current operation is a write operation, a latest flag to indicate that the second entry is no longer the latest of multiple operations directed to an address.

9. The non-transitory computer-readable storage medium of claim 8 , wherein the determining whether the current operation collides with the prior operation comprises checking a second data structure for an entry that has an address that matches the address to which the current operation is directed.

10. The non-transitory computer-readable storage medium of claim 8 , wherein the processing device is further to increment a counter associated with the first buffer identifier.

11. The non-transitory computer-readable storage medium of claim 8 , wherein the first data structure is stored in a memory outside of the memory component.

12. The non-transitory computer-readable storage medium of claim 8 , wherein the processing device is further to:

assign a third operation identifier to a subsequent operation directed to a memory component, the third operation identifier having an entry in the first data structure that associates the third operation identifier with a plurality of buffer identifiers; and

update, in response to determining that the subsequent operation collides with the current operation and that the subsequent operation is a read operation, the plurality of buffer identifiers to include a buffer identifier associated with the current operation.

13. The non-transitory computer-readable storage medium of claim 12 , wherein the updating comprises replacing a buffer identifier included in the plurality of buffer identifiers with the buffer identifier associated with the current operation.

14. The non-transitory computer-readable storage medium of claim 12 , wherein the processing device is further to:

determine that the prior operation is a read operation; and

update, in response to determining that the subsequent operation collides with the prior operation and that the prior operation is a read operation, the entry in the first data structure associated with the second operation identifier to identify the third operation identifier.

15. A system comprising:

a memory component; and

a processing device, operatively coupled with the memory component, to:

assign a first operation identifier to a current operation directed to the memory component, the first operation identifier having a first entry in a first data structure that associates the first operation identifier with a first buffer identifier;

determine whether the current operation collides with a prior operation assigned a second operation identifier, the second operation identifier having a second entry in the first data structure that associates the second operation identifier with a second buffer identifier;

determine whether the current operation is a read or a write operation;

update, in response to determining that the current operation collides with the prior operation and that the current operation is a write operation, a latest flag to indicate that the second entry is no longer the latest of multiple operations directed to an address; and

increment a counter associated with the first buffer identifier.

16. The system of claim 15 , wherein the determining whether the current operation collides with the prior operation comprises checking a second data structure for an entry that has an address that matches the address to which the current operation is directed.

17. The system of claim 15 , wherein the first data structure is stored in a memory outside of the memory component.

18. The system of claim 15 , wherein the processing device is further to:

assign a third operation identifier to a subsequent operation directed to a memory component, the third operation identifier having an entry in the first data structure that associates the third operation identifier with a plurality of buffer identifiers; and

update, in response to determining that the subsequent operation collides with the current operation and that the subsequent operation is a read operation, the plurality of buffer identifiers to include a buffer identifier associated with the current operation.

19. The system of claim 18 , wherein the updating comprises replacing a buffer identifier included in the plurality of buffer identifiers with the buffer identifier associated with the current operation.

20. The system of claim 18 , wherein the processing device is further to:

determine that the prior operation is a read operation; and

update, in response to determining that the subsequent operation collides with the prior operation and that the prior operation is a read operation, the entry in the first data structure associated with the second operation identifier to identify the third operation identifier.
