Semiconductor memory device with efficient inclusion of control circuits
Abstract:
A semiconductor memory device includes memory cell arrays that include a plurality of memory cells. A first control circuit with control transistors of a first conductivity type is in a first region below the memory cell arrays. A second control circuit includes a first transistor of a first conductivity type connected in parallel to a second transistor of a second conductivity type. One of the first and second transistors is connected to an end of at least one control transistor. The second control circuit delivers a voltage to the plurality of control transistors. The first transistor is disposed in the first region. The second transistor is disposed in a second region adjacent to the first region. The second region is below a gap between adjacent memory cell arrays.
