MEMORY CONTROLLER, MEMORY SYSTEM, AND ACCESS CONTROL METHOD OF FLASH MEMORY
First Claim
1. A memory controller that controls access to a flash memory in which data is written in a page size unit according to data-write request information, whereinthe memory controller adds dummy data to write data by referring to instruction information about a descriptor transfer of the write data if a size of the write data to be written according to the data-write request information does not match the page size unit, thereby adjusting the size of the write data to the page size unit and then outputs the write data.

19. A method of controlling access to a flash memory in which a memory controller controls access to a flash memory in which data is written in a page size unit according to data-write request information, the method comprising:
-
the memory controller acquiring write data to be written into the flash memory according to the data-write request information; the memory controller adding dummy data to the write data by referring to instruction information about a descriptor transfer of the write data if a size of the write data to be written according to the data-write request information does not match the page size unit and adjusting the size of the write data to the page size unit; and the memory controller outputting the write data by referring the instruction information.
