METHOD AND DEVICE FOR STORING DATA IN A FLASH MEMORY USING ADDRESS MAPPING FOR SUPPORTING VARIOUS BLOCK SIZES

摘要

The present invention relates to a method and device for storing data in a flash memory using address mapping for supporting various block sizes. A storage device determines the size of a block that a host system uses on the basis of the size of data that the host system requests and uses the determined block size as a mapping unit. Additionally, the storage device divides a logical address space into at least one area, and maps an address using the minimum units of different mappings in each divided area.

主权项

1. A storage device comprising:
a flash memory to store data; a block size determining unit to determine a size of a block used by a host system connected to the storage device; and an address mapping management unit to map a logical address of the storage device to a physical address of the flash memory, using the determined size as a unit of mapping.
