PURPOSE: A memory device and its internal control method are provided to achieve efficient access and current consumption reduction. CONSTITUTION: A memory device includes a memory array(36) including a plurality of memory cells arranged in accordance with the first address and the second address which define a logical address map indicating a logical shape of the memory array. An address map changing unit(30,31,32,33,34,35) operatively coupled to the memory array receives the first address signal for generating the first address and the second address signal for generating the second address, wherein the address map changing unit is capable of changing the logical address map by altering a part of one of the first address signal and the second address signal.
