Abstract

An electronic system includes: an interface block of a storage device configured to process system information from a system device; a memory block of the storage device, coupled to the interface block, partitioned by the interface block configured to process the system information for partitioning the memory block; and a storage block of a storage device, coupled to the memory block, configured to access a data block of the storage block provided to the system device.

First claim

What is claimed is:

1. A storage device comprising:
a memory block configured as a memory cache;
an interface block, coupled to the memory block, configured to process system information to determine a number of threads and a number of requests for each of the threads received from a system device;
a partition block, included in the interface block, configured to partition the memory block into shared partitions and private partitions, wherein:
each of the shared partitions are evenly divided based on the number of threads,
the private partitions are proportionally divided based on the number of requests for each of the threads; and

a storage block, coupled to the memory block, configured to provide a data block.

2. The device as claimed in claim 1 wherein the interface block is configured to identify the system information.

3. The device as claimed in claim 1 wherein the interface block is configured to associate a request of the system information to a partition of the memory block.

4. The device as claimed in claim 1 wherein the partition block is configured to dynamically change a partition of the memory block.

5. The device as claimed in claim 1 further comprising a transition block, coupled to the storage block, configured to translate the storage block to the system device.

6. The device as claimed in claim 1 wherein the partition block is configured to associate requests of the system information to the thread of the system information.

7. The device as claimed in claim 1 wherein the interface block, including the partition block, is configured to process the request with a common identification for distinguishing the request.

8. A method of operation of a storage device comprising:
processing system information to determine a number of threads and a number of requests for each of the threads received from a system device;
partitioning a memory block, configured as a memory cache, into shared partitions and private partitions by an interface block, wherein:
each of the shared partitions are evenly divided based on the number of threads,
the private partitions are proportionally divided on the number of requests for each of the threads; and

accessing a storage block to provide a data block.

9. The method as claimed in claim 8 wherein partitioning the memory block by the interface block includes identifying the system information.

10. The method as claimed in claim 8 wherein partitioning the memory block by the interface block includes associating a request of the system information to a partition of the memory block.

11. The method as claimed in claim 8 wherein partitioning the memory block by the interface block includes a partition block for dynamically changing a partition of the memory block.

12. The method as claimed in claim 8 further comprising translating with a transition block configured to translate the storage block to the system device.

13. The method as claimed in claim 8 further comprising associating with a partition block configured to associate requests of the system information to a thread of the system information.

14. The method as claimed in claim 8 wherein processing system information includes processing the request with a common identification for distinguishing the request.

15. A non-transitory computer readable medium including stored thereon instructions for operating a storage device, comprising:
processing system information to determine a number of threads and a number of requests for each of the threads received from a system device;
partitioning a memory block, configured as a memory cache, into shared partitions and private partitions by an interface block, wherein:
each of the shared partitions are evenly divided based on the number of threads,
the private partitions are proportionally divided based on the number of requests for each of the threads; and

accessing a storage block to provide a data block.

16. The medium as claimed in claim 15 wherein partitioning the memory block by the interface block includes identifying the system information.

17. The medium as claimed in claim 15 wherein partitioning the memory block by the interface block includes associating a request of the system information to a partition of the memory block.

18. The medium as claimed in claim 15 wherein partitioning the memory block by the interface block includes a partition block for dynamically changing a partition of the memory block.

19. The medium as claimed in claim 15 further comprising translating with a transition block configured to translate the storage block to the system device.

20. The medium as claimed in claim 15 further comprising associating with a partition block configured to associate requests of the system information to a thread of the system information.
