<P>PROBLEM TO BE SOLVED: To provide a memory device and a memory system capable of writing data without reduction of data write speed regardless of the logical address of the data, and reducing power consumption. <P>SOLUTION: A memory controller 200 comprises: a logical-physical conversion table 204; an erased physical block management unit 206 that manages erased physical block addresses, non-volatile memories thereof, and each number of erased physical blocks per a non-volatile memory; an erasable physical block management unit 205 that manages erasable physical block addresses, non-volatile memories thereof, and each number of erasable physical blocks per a non-volatile memory; and a memory control unit 207. The memory control unit writes data on a first physical block in one non-volatile memory that is under the management of the erased physical block management unit, and erases, in parallel therewith, a second physical block in another non-volatile memory that is under the management of the erasable physical block management unit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
