  • Publication number: 20140304453
    Abstract: This invention discloses methods for implementing a flash translation layer in a computer subsystem comprising a flash memory and a random access memory (RAM). According to one disclosed method, the flash memory comprises data blocks for storing real data and translation blocks for storing address-mapping information. The RAM includes a cache space allocation table and a translation page mapping table. The cache space allocation table may be partitioned into a first cache space and a second cache space. Upon receiving an address-translating request, the cache space allocation table is searched to identify if an address-mapping data structure that matches the request is present. If not, the translation blocks are searched for the matched address-mapping data structure, where the physical page addresses for accessing the translation blocks are provided by the translation page mapping table. The matched address-translating data structure is also used to update the cache space allocation table.
