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; and

updating a latest flag to indicate that the first entry is a latest operation directed to an address, wherein the latest flag is updated:

(1) in response to determining that the current operation collides with the prior operation and that the current and prior operations are read operations, or

(2) in response to determining that the current operation does not collide with a prior operation.

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 value 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 a third entry in the first data structure that associates the third operation identifier with a third buffer identifier; 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 third buffer identifier to include the first buffer identifier associated with the current operation.

6. The method of claim 5 , wherein the updating comprises replacing the third buffer identifier with the first buffer identifier.

7. The method of claim 5 , further comprising:

determining that the current operation is a read operation; and

updating, in response to determining that the subsequent operation collides with the current operation and that the current operation is a read operation, the first entry in the first data structure associated with the first 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; and

update a latest flag to indicate that the first entry is a latest operation directed to an address, wherein the latest flag is updated:

(1) in response to determining that the current operation collides with the prior operation and that the current and prior operations are read operations, or

(2) in response to determining that the current operation does not collide with a prior operation.

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 value 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 a third entry in the first data structure that associates the third operation identifier with a third buffer identifier; 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 third buffer identifier to include the first buffer identifier associated with the current operation.

13. The non-transitory computer-readable storage medium of claim 12 , wherein the updating comprises replacing the third buffer identifier with the first buffer identifier.

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 current operation and that the current operation is a read operation, the first entry in the first data structure associated with the first 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 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;

update a latest flag to indicate that the first entry is a latest operation directed to an address, wherein the latest flag is updated:

(1) in response to determining that the current operation collides with the prior operation and that the current and prior operations are read operations, or

(2) in response to determining that the current operation does not collide with a prior operation; 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 value 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 a third entry in the first data structure that associates the third operation identifier with a third buffer identifier; 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 third buffer identifier to include the first buffer identifier associated with the current operation.

19. The system of claim 18 , wherein the updating comprises replacing the third buffer identifier with the first buffer identifier.

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 current operation and that the current operation is a read operation, the first entry in the first data structure associated with the first operation identifier to identify the third operation identifier.
