Large data read techniques
View Patent ↗Devices and techniques are disclosed herein for more efficiently exchanging large amounts of data between a host and a storage system. In an example, a read command can optionally include a read-type indicator. The read-type indicator can allow for exchange of a large amount of data between the host and the storage system using a single read command.
1. A memory device comprising:
a memory array; and
a controller, configured to perform operations comprising:
receiving a read command from a host device, wherein the read command comprises a location identifier for retrieving read data from the memory array;
determining that the read command comprises an indication indicating a read-type;
in response to the indication being a certain value:
identifying a parameter list received from the host device, wherein the parameter list comprises one or more location identifiers for retrieving additional read data from the memory array;
retrieving the read data and the additional read data from the memory array using the location identifier and the one or more location identifiers; and
transmitting the read data and the additional read data to the host device.
2. The memory device of claim 1 , wherein the location identifier comprises a logical block address of the read data.
3. The memory device of claim 1 , wherein the location identifier comprises a he read data on the memory array.
4. The memory device of claim 1 , wherein the operations further comprise:
in response to the indication being another value different from the certain value:
retrieving the read data from the memory array using the location identifier; and
transmitting the read data to the host device.
5. The memory device of claim 1 , wherein the one or more location identifiers comprises a physical address of the additional read data on the memory device.
6. The memory device of claim 1 , wherein the one or more location identifiers comprise at least two non-contiguous addresses.
7. The memory device of claim 1 , wherein the operations further comprise:
transmitting the read data and the additional read data to the host device without receiving any additional read command from the host device.
8. A controller of a memory device, the controller is configured to perform operations comprising:
receiving a read command from a host device, wherein the read command comprising a location identifier for retrieving read data;
determining that the read command comprises an indication indicating a read-type;
in response to the indication being a certain value:
identifying a parameter list received from the host device, wherein the parameter list comprises one or more location identifiers for retrieving additional read data;
retrieving the read data and the additional read data from the memory device using the location identifier and the one or more location identifiers; and
transmitting the read data and the additional read data to the host device.
9. The controller of claim 8 , wherein the location identifier comprises a logical block address of the read data.
10. The controller of claim 8 , wherein the location identifier comprises a physical address of the read data on the memory device.
11. The controller of claim 8 , wherein the operations further comprise:
in response to the indication being another value different from the certain value:
retrieving the read data from the memory device using the location identifier; and
transmitting the read data to the host device.
12. The controller of claim 8 , wherein the one or more location identifiers comprises a physical address of the additional read data on the memory device.
13. The controller of claim 8 , wherein the one or more location identifiers comprise at least two non-contiguous addresses.
14. The controller of claim 8 , wherein the operations further comprise:
transmitting the read data and the additional read data to the host device without receiving any additional read command from the host device.
15. A non-transitory machine-readable medium, storing instructions, which when executed by a memory device, causes the memory device to perform operations comprising:
receiving a read command from a host device, wherein the read command comprising a location identifier for retrieving read data;
determining that the read command comprises an indication indicating a read-type;
in response to the indication being a certain value:
identifying a parameter list received from the host device, wherein the parameter list comprises one or more location identifiers for retrieving additional read data;
retrieving the read data and the additional read data from the memory device using the location identifier and the one or more location identifiers; and
transmitting the read data and the additional read data to the host device.
16. The non-transitory machine-readable medium of claim 15 , wherein the location identifier comprises a logical block address of the read data.
17. The non-transitory machine-readable medium of claim 15 , wherein the location identifier comprises a physical address of the read data on the memory device.
18. The non-transitory machine-readable medium of claim 15 , wherein the operations further comprise:
in response to the indication being another value different from the certain value:
retrieving the read data from the memory device using the location identifier; and
transmitting the read data to the host device.
19. The non-transitory machine-readable medium of claim 15 , wherein the one or more location identifiers comprises a physical address of the additional read data on the memory device.
20. The non-transitory machine-readable medium of claim 15 , wherein the one or more location identifiers comprise at least two non-contiguous addresses.
