Patent ID: 6847576

Claim:
An integrated circuit memory device comprising: a first memory block that comprises first and second memory array banks and a first peripheral circuit, the first peripheral circuit being disposed between the first and second memory array banks such that a length of a first data path from the first memory array bank to the first peripheral circuit is about equal to a length of a second data path from the second memory array bank to the first peripheral circuit; a second memory block that comprises third and fourth memory array banks and a second peripheral circuit, the second peripheral circuit being disposed between the third and fourth memory array banks such that a length of a first data path from the third memory array bank to the second peripheral circuit is about equal to a length of a fourth data path from the second memory array bank to the second peripheral circuit; a first control circuit block disposed between the first memory block and the second memory block; a third memory block that comprises fifth and sixth memory array banks and a third peripheral circuit, the third peripheral circuit being disposed between the fifth and sixth memory array banks such that a length of a fifth data path from the fifth memory array bank to the third peripheral circuit is about equal to a length of a sixth data path from the sixth memory array bank to the third peripheral circuit, wherein the third memory block is disposed adjacent to the first memory block on the same side of the first control circuit block; and a fourth memory block comprising seventh and eight memory array banks and a fourth peripheral circuit, the fourth peripheral circuit being disposed between the seventh and eighth memory array banks such that a length of a seventh data path from the seventh memory array bank to the fourth peripheral circuit is about equal to a length of an eighth data path from the eighth memory array bank to the fourth peripheral circuit, wherein the fourth memory block is disposed adjacent to the second memory block on the same side of the first control circuit block.
