Abstract

Claims (70)

1. A method, comprising:

receiving a set of data to write to a solid state drive;

determining a logical address to the set of data;

setting a logical offset of the set of data to be equal to a physical block offset modulo of the physical address of the data; and

writing the set of data to the solid state drive in locations on the solid state drive that accept a size of the address of the set of data, wherein the physical block offset modulo of the physical address of the data is equal to one unique slot arrangement for each program unit.

2. The method according to claim 1 , further comprising:

writing the set of data to a buffer prior to the writing of the set of data to the solid state drive.

3. The method according to claim 2 , wherein the buffer has at least two buffers.

4. The method according to claim 3 , wherein a number of the at least two buffers is provided by a mathematical relationship.

5. A method, comprising:

receiving a set of data to write to a solid state drive;

determining a logical address to the set of data;

setting a logical offset of the set of data to be equal to a physical block offset modulo of the physical address of the data; and

writing the set of data to the solid state drive in locations on the solid state drive that accept a size of the address of the set of data writing the set of data to a buffer prior to the writing of the set of data to the solid state drive wherein the buffer has at least two buffers wherein a number of the at least two buffers is provided by a mathematical relationship, wherein the mathematical relationship is a straight line relationship in log space pertaining to a graph of a padding fraction verses a number of buffers.

6. The method according to claim 1 , wherein the physical block offset is equal to a number of possible allowed alignments.

7. The method according to claim 1 , wherein the writing of the set of data is in a reordered configuration from an original configuration for the set of data.

8. The method according to claim 6 , wherein the number of possible allowed alignments is chosen by one of a user and a system architect.

9. A method, comprising:

receiving a set of data to write to a solid state drive;

determining a logical address to the set of data;

setting a logical offset of the set of data to be equal to a physical block offset modulo of the physical address of the data; and

writing the set of data to the solid state drive in locations on the solid state drive that accept a size of the address of the set of data wherein the physical block offset is equal to a number of possible allowed alignments wherein the number of alignments is one unique slot arrangement for each program unit.

10. The method according to claim 2 , further comprising:

padding the set of data to fill the buffer.

11. The method according to claim 7 , wherein the writing occurs when a buffer is full of data.

12. The method according to claim 1 , further comprising:

establishing a maximum number of buffers; and

comparing a number of buffers created to the maximum number of buffers.

13. The method according to claim 12 , further comprising:

creating a new buffer for data to be added when the number of buffers created does not equal the maximum number of buffers.

14. The method according to claim 1 , further comprising:

checking if a further command to write a set of data is received.

15. The method according to claim 14 , further comprising:

writing all data in a buffer if no further command is received.

16. The method according to claim 13 , further comprising:

writing the data to the solid state drive when either of the buffer or the new buffer are full.

17. The method according to claim 16 , further comprising:

padding at least one of the buffer and the new buffer to fill the buffer.

18. The method according to claim 1 , wherein a maximum size of the logical address is 4 KB.

19. The method according to claim 1 , wherein the writing the set of data to the solid state drive in locations on solid state drive that accept the size of the address of the set of data is accomplished at a plurality of die.

20. The method according to claim 1 , wherein the set of data to be written is less than a page.

21. A method, comprising:

receiving a set of data to write to a memory device;

determining a logical address to the set of data;

setting a logical offset of the set of data to be equal to a physical block offset modulo of the physical address of the data;

determining if a maximum number of memory buffers has been reached;

determining if a new buffer is needed for storage of information;

creating a new buffer from memory when a new buffer is needed;

writing the set of data to the new buffer;

determining if the new buffer from memory is full with the set of data; and

writing the set of data from the new buffer to the memory device when the new buffer is full, wherein the physical block offset modulo of the physical address of the data is equal to one unique slot arrangement for each program unit.

22. The method according to claim 21 , wherein the memory device is a solid state drive.

23. The method according to claim 21 , wherein the maximum number of memory buffers is 64.

24. The method according to claim 21 , wherein the memory buffers are created in a volatile memory system.

25. A method, comprising:

receiving a set of data to write to a memory device;

determining a logical address to the set of data;

setting a logical offset of the set of data to be equal to a physical block offset modulo of the physical address of the data;

determining if a maximum number of memory buffers has been reached;

determining if a new buffer is needed for storage of information;

creating a new buffer from memory when a new buffer is needed;

writing the set of data to the new buffer;

determining if the new buffer from memory is full with the set of data;

determining if more data is available for processing from a host; and

writing contents of the new buffer to the memory device when no more data is available from the host, wherein the physical block offset modulo of the physical address of the data is equal to one unique slot arrangement for each program unit.
