A system and a method for processing a read request are provided to process a read request with respect to a flash memory irrespective of a processor and maintain synchronization for a translation table while sharing the translation table with the processor. A read request processing system(401) includes a read request receiver(410), a physical address validity determination unit(420), a physical address receiver(440), and a read request unit(450). The read request receiver receives a read request including logical address information from a host interface. The physical address validity determination unit determines whether a physical address corresponding to a logical address included in the logical address information is valid in a translation table with reference to the translation table. The physical address receiver receives the physical address when the physical address is valid in the translation table. The read request unit requests data corresponding to the physical address to be read from a flash memory.
