STORAGE MEDIUM CONTROLLER, STORAGE MEDIUM CONTROL METHOD, AND PROGRAM

PROBLEM TO BE SOLVED: To speed up data writing in a flash memory. SOLUTION: In writing data, block switching is not performed but data to be written are added by the page. At the same time, a logical page address is defined and stored for every page data so that a logical position of page data may become clear. When there is no blank page in an original block, an additional block with the same LBA as the original block (original block) is created and addition by the page is performed to the additional block. The additional block is given the same LBA as the original block. Thus, there is no need to perform block exchange processing every time page data are written, for example.
