Patent ID: 8274826

Claim:
A NAND type flash memory comprising: a first memory plane with first and second NAND blocks; a second memory plane with third and fourth NAND blocks; a first transfer transistor with a control terminal, a first potential transfer terminal, and a second potential transfer terminal, and disposed between the first and second memory planes, the first potential transfer terminal being commonly connected to a first word line in the first NAND block and a second word line in the third NAND block; a second transfer transistor with a control terminal, a first potential transfer terminal, and a second potential transfer terminal, and disposed at a first end on a side of the first memory plane that is opposite the second memory plane, the first potential transfer terminal being connected to a third word line in the second NAND block; and a third transfer transistor with a control terminal, a first potential transfer terminal, and a second potential transfer terminal, and disposed at a second end on a side of the second memory plane that is opposite the first memory plane, the first potential transfer terminal being connected to a fourth word line in the fourth NAND block.
