MEMORY CONTROLLER, FLASH MEMORY SYSTEM, AND CONTROL METHOD FOR FLASH MEMORY

摘要

PROBLEM TO BE SOLVED: To increase the processing efficiency of the writing of user data and additional data to a flash memory. SOLUTION: A flash memory system 1 is removably attached to a host system 4 to write user data supplied from the host system 4 and corresponding additional data to the flash memory 2. A memory controller 3 forming the flash memory system 1 comprises a function of holding the user data given from the host system 4 and the additional data corresponding to the user data and a data transfer function of transferring the user data and additional data held to the flash memory, and writes a plurality of sets of user data and additional data alternately to a page in the flash memory 2 and writes the user data and additional data to consecutive positions. The number of times of address transmission can be thereby reduced. COPYRIGHT: (C)2006,JPO&NCIPI
