Abstract
A file manager and buffer cache manager generate access information for accessing a flash ROM in units of blocks on the basis of an access request designated by a user program. When the access request is a data read request, a flash disk driver calculates an access address to the flash ROM on the basis of a block designated by the access information, and sends back the calculated access address to the buffer cache manager. The buffer cache manager reads out data from the flash ROM using the received access address, and directly transfers the obtained data to a memory area managed by the user program.
