SYSTEM AND METHOD FOR PROCESSING READ REQUEST

摘要

A system and a method for processing a read request are provided to process a read request for a flash memory independently of a processor and confirm data distributed in the flash memory and a write buffer with a single read request by using descriptor arrangement. A read request processing system(401) includes a read request receiver(410) for receiving a read request having logical address information from a host interface, a physical address validity determination unit(420) for determining whether a physical address corresponding to a logical address included in the logical address information is valid in a translation table, a physical address receiver(440) for receiving the physical address with reference to the translation table when the physical address is valid in the translation table, and a read request unit(450) for requesting data corresponding to the physical address to be read from a flash memory. The read request processing system operates independently of a processor.
