<p><P>PROBLEM TO BE SOLVED: To improve performance deterioration by randomization release processing. <P>SOLUTION: The memory system includes: a semiconductor memory in which randomized randomization data are written; and an MPU which switches, when the randomization data are read, a first mode for storing data after releasing the randomization in a buffer while releasing the randomization of the randomization data and a second mode for storing the randomization data in the buffer according to use of reading. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
