Abstract

A data storage device and method are disclosed for reducing an impact of a wordline-to-wordline short when storing video. In one embodiment, a data storage device is provided comprising a memory comprising a plurality of worklines and one or more processors. The one or more processors, individually or in combination, are configured to: receive, from a host, a plurality of video frames for storage in the memory; receive, from the host, information regarding an order of the plurality of video frames; and store the plurality of video frames in the memory such that consecutive video frames are stored in non-consecutive wordlines as protection against a wordline-to-wordline short. Other embodiments are provided.

Claims (35)

1 . A data storage device comprising:

a memory comprising a plurality of wordlines; and

one or more processors, individually or in combination, configured to:

receive, from a host, a plurality of video frames for storage in the memory;

negotiate a communication mechanism with the host for receiving information regarding an order of the plurality of video frames;

receive, from the host, information regarding the order of the plurality of video frames; and

store the plurality of video frames in the memory such that consecutive video frames are stored in non-consecutive wordlines as protection against a wordline-to-wordline short.

2 . The data storage device of claim 1 , wherein the one or more processors, individually or in combination, are further configured to store consecutive video frames in different open blocks.

3 . The data storage device of claim 1 , wherein the information regarding the order of the plurality of video frames comprises frame numbers.

4 . The data storage device of claim 3 , wherein the host is configured to segregate the plurality of video frames from a video file and number the plurality of video frames incrementally with the frame numbers.

5 . The data storage device of claim 1 , wherein the information regarding the order of the plurality of video frames is stored in headers of the plurality of video frames, wherein a header of given video frame of the plurality of video frames identifies that video frame's position in the order.

6 . The data storage device of claim 1 , wherein the information regarding the order of the plurality of video frames is received as individual write commands.

7 . The data storage device of claim 1 , wherein the plurality of video frames is stored the memory without using a dual write operation.

8 . The data storage device of claim 1 , wherein the plurality of video frames is stored the memory without using an enhanced post-write read (EPWR) operation.

9 . The data storage device of claim 1 , wherein the plurality of video frames is stored the memory without using an exclusive-or (XOR) operation to generate XOR parity.

10 . The data storage device of claim 1 , wherein the memory comprises a three-dimensional memory.

11 . A method comprising:

performing in a data storage device in communication with a host, the data storage device comprising a memory comprising a plurality of wordlines:

receiving, from the host, a plurality of video frames for storage in the memory;

negotiating a communication mechanism with the host for receiving information for identifying which video frames of the plurality of video frames are adjacent;

receiving, from the host, the information for identifying which video frames of the plurality of video frames are adjacent; and

storing adjacent video frames of plurality of video frames in non-adjacent wordlines in the memory.

12 . The method of claim 11 , wherein the adjacent video frames of plurality of video frames are stored in different open blocks.

13 . The method of claim 11 , wherein the information for identifying which video frames of the plurality of video frames are adjacent comprises frame numbers.

14 . The method of claim 11 , wherein the communication mechanism is negotiated after power on.

15 . The method of claim 11 , wherein the communication mechanism is negotiated during runtime.

16 . The method of claim 11 , wherein the communication mechanism comprises a protocol-specific mechanism.

17 . The method of claim 16 , wherein the protocol-specific mechanism comprises a stream identifier.

18 . A data storage device comprising:

a memory comprising a plurality of wordlines; and

means for:

receiving, from a host, a plurality of video frames for storage in the memory;

negotiating a communication mechanism with the host for receiving information for identifying which video frames of the plurality of video frames are adjacent;

receiving, from the host, the information for identifying which video frames of the plurality of video frames are adjacent; and

storing adjacent video frames of plurality of video frames in non-adjacent wordlines in the memory.
