Abstract
A cell array in the semiconductor memory device is divided into two blocks. Each of control signal lines for transmission of control signals are also divided into a first portion and a second portion correspondingly to the blocks. A repeater circuit that relays a control signal is provided between the two portions. The repeater circuit does not output the control signal from the first portion to the second portion, as long as a block that receives the control signal via the first portion is selected.
