Electronic storage device
A solution for reducing erase cycles in an electronic storage device that uses at least one erase-limited memory device is disclosed.
1. A method comprising:
mapping a primary address to a set of minimum erasable locations in a storage device;
initializing the set;
obtaining and storing initialization parameters; and
initializing a section selection sequence that determines a first minimum writeable location in the set.
2. The method of claim 1 , wherein the set of minimum erasable locations comprises a flash block in a non-volatile memory device.
3. The method of claim 1 , wherein the set of minimum erasable locations comprises a plurality of flash blocks in a non-volatile memory device.
4. The method of claim 1 , wherein initializing the set comprises erasing the set.
5. The method of claim 1 , wherein the first minimum writable location comprises a flash section.
6. The method of claim 1 , wherein the initialization parameters comprises at least one of the following: a size of a minimum erasable location; a size of a minimum writeable location; a number of minimum erasable locations mapped to the primary address; a sequence range; and an invalid flash section location.
7. The method of claim 6 , wherein the size of the minimum writable location comprises a flash block page.
8. The method of claim 1 , wherein the section selection sequence indicates an available minimum writable location that can receive a write operation to store data associated with the primary address that is mapped to the set.
9. The method of claim 8 , wherein the available minimum writable location is no longer in an erased state after a write operation is performed on the available minimum writable location and wherein the section selection sequence indicates another available minimum writable location that can receive a second write operation to store data associated with the primary address that is mapped to the set.
10. An apparatus comprising:
a storage device configured to map a primary address to a set of minimum erasable locations in a storage device, initialize the set, obtain and store initialization parameters, and initialize a section selection sequence that determines a first minimum writeable location in the set.
11. The apparatus of claim 10 , wherein the set of minimum erasable locations comprises a flash block in a non-volatile memory device.
12. The apparatus of claim 10 , wherein the set of minimum erasable locations comprises a plurality of flash blocks in a non-volatile memory device.
13. The apparatus of claim 10 , wherein the storage device is configured to initialize the set by erasing the set.
14. The apparatus of claim 10 , wherein the first minimum writable location comprises a flash section.
15. The apparatus of claim 10 , wherein the initialization parameters comprises at least one of the following: a size of a minimum erasable location; a size of a minimum writeable location; a number of minimum erasable locations mapped to the primary address; a sequence range; and an invalid flash section location.
16. The apparatus of claim 15 , wherein the size of the minimum writable location comprises a flash block page.
17. The apparatus of claim 10 , wherein the section selection sequence indicates an available minimum writable location that can receive a write operation to store data associated with the primary address that is mapped to the set.
18. The apparatus of claim 17 , wherein the available minimum writable location is no longer in an erased state after a write operation is performed on the available minimum writable location and wherein the section selection sequence indicates another available minimum writable location that can receive a second write operation to store data associated with the primary address that is mapped to the set.
19. An article of manufacture, comprising:
a non-transient computer-readable medium having stored thereon instructions operable to permit an apparatus to:
map a primary address to a set of minimum erasable locations in a storage device;
initialize the set;
obtain and store initialization parameters; and
initialize a section selection sequence that determines a first minimum writeable location in the set.
