Accessing data in memory
View Patent ↗The present disclosure includes apparatuses and methods related to accessing data in memory. One example method comprises storing data associated with a first operation in a first sense amplifier responsive to receiving a request to perform a second operation, and performing the second operation associated with a row of memory cells while the data associated with the first operation is being stored in the first sense amplifier.
1. A system, comprising:
a host; and
a memory device coupled to the host and configured to:
receive, while a first operation is being performed, a request to perform a second operation from the host; and
perform, while data associated with the first operation is stored in sensing circuitry of the memory device, the second operation using the sensing circuitry.
2. The system of claim 1 , wherein the memory device is configured to provide a result of the second operation to the host.
3. The system of claim 2 , wherein the data associated with the first operation is stored in an array of memory cells of the memory device subsequent to the result of the second operation being provided to the host.
4. The system of claim 1 , wherein the second operation associated with the request received from the host has a priority over the first operation.
5. The system of claim 4 , wherein the memory device performs the first operation independently from the host.
6. The system of claim 1 , wherein the sensing circuitry includes a first sense amplifier and a second amplifier, and wherein the memory device is configured to:
store, in response to receipt of the request to perform the first operation, the data associated with the first operation in the first sense amplifier; and
perform, while the data associated with the first operation is being stored in the first sense amplifier, the second operation using the second sense amplifier.
7. The system of claim 6 , wherein:
the first sense amplifier is coupled to a compute component of the sensing circuitry; and
the controller is configured to continue a performance of the first operation via the compute component, while the controller performs the second operation using the sense amplifier.
8. A system, comprising:
a host; and
a memory device coupled to the host and configured to:
receive, while a first operation is being performed, a request to perform a second operation from the host; and
initiate, prior to a completion of the first operation, the second operation using the sensing circuitry such that the controller performs the first operation while data associated with the first operation is stored in sensing circuitry.
9. The system of claim 8 , wherein the data associated with the first operation is stored in the sensing circuitry until a completion of the second operation.
10. The system of claim 8 , wherein the controller is configured to store, upon a completion of the second operation, the data associated first operation back to an array of memory cells without firing a column decode signal.
11. The system of claim 8 , wherein the system comprises a server.
12. The system of claim 8 , wherein the controller comprises a state machine.
13. The system of claim 8 , wherein the controller comprises a sequencer.
14. The system of claim 8 , wherein the host and the memory device are located on a same integrated circuit.
15. The system of claim 14 , wherein the first operation is a compute operation.
16. A method, comprising:
receiving, while performing a first operation using sensing circuitry, a request to perform a second operation from a host;
determining whether to pause the first operation based on an priority comparison between the first operation and the second operation; and
pausing, responsive to determining that the second operation is given a higher priority over the first operation, the first operation to initiate the second operation while data associated with the first operation is being stored in the sensing circuitry.
17. The method of claim 16 , further comprising completing, responsive to determining that the second operation is not given a higher priority over the first operation, the first operation prior to initiating the second operation.
18. The method of claim 16 , wherein the second operation requested from the host is given a higher priority over the first operation being performed independently.
19. The method of claim 16 , wherein storing the data associated with the first operation in the sensing circuitry comprises storing the data associated with the first operation in a sense amplifier of the sensing circuitry.
20. The method of claim 19 , wherein initiating the second operation comprises using another sensing amplifier of the sensing circuitry to perform the second operation.
