Abstract

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.

First claim

What is claimed is:

1 . A method comprising:
sending, from a host device to a memory device, a read command comprising:
a location identifier for retrieving read data from the memory device; and
an indication indicating a read-type of the read command;
sending, from the host device to the memory device, a parameter list comprising one or more location identifiers for retrieving additional read data from the memory device; and in response to the indication being a certain value, receiving, by the host device from the memory device, the read data and the additional read data retrieved using the location identifier and the one or more location identifiers.

2 . The method of claim 1 , wherein the location identifier comprises a logical block address of the read data.

3 . The method of claim 1 , wherein the location identifier comprises a physical address of the read data on the memory device.

4 . The method of claim 1 , wherein the one or more location identifiers comprises a physical address of the additional read data on the memory device.

5 . The method of claim 1 , wherein the one or more location identifiers comprise at least two non-contiguous addresses.

6 . The method of claim 1 , comprising:
receiving, by the host device from the memory device, the read data and the additional read data without sending any additional read command to the memory device.

7 . The method of claim 1 , comprising:
in response to the indication being another value different from the certain value, receiving, by the host device from the memory device, the read data retrieved using the location identifier.

8 . A method comprising:
receiving, by a memory device, a read command from a host device, wherein the read command comprises a location identifier for retrieving read data from a 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.

9 . The method of claim 8 , wherein the location identifier comprises a logical block address of the read data.

10 . The method of claim 8 , wherein the location identifier comprises a physical address of the read data on the memory device.

11 . The method of claim 8 , comprising:
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 method 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 method of claim 8 , wherein the one or more location identifiers comprise at least two non-contiguous addresses.

14 . The method of claim 8 , comprising:
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 system comprising:
a memory device; and a host device configured to:
send, to the memory device, a parameter list comprising one or more location identifiers for retrieving additional read data from the memory device;
send, to the memory device, a read command comprising:
at least one location identifiers for retrieving read data from the memory device; and
an indication indicating a read-type of the read command; and

in response to the indication being a certain value, receive, from the memory device, the read data and the additional read data retrieved using the at least one location identifiers and the one or more location identifiers.

16 . The system of claim 15 , wherein the at least one location identifiers comprises a logical block address of the read data.

17 . The system of claim 15 , wherein the at least one location identifiers comprises a physical address of the read data on the memory device.

18 . The system of claim 15 , wherein the one or more location identifiers comprises a physical address of the additional read data on the memory device.

19 . The system of claim 15 , wherein the one or more location identifiers comprise at least two non-contiguous addresses.

20 . The system of claim 15 , wherein the host device is configured to receive the read data and the additional read data from the memory device without sending any additional read command to the memory device.
