Abstract
Provided is a semiconductor device including: a memory cell array including a plurality of memory cells disposed in a matrix; and a peripheral circuit adjacent to the memory cell array. Each of the memory cells includes: a capacitive element including a lower electrode having a cylinder shape extending in a direction perpendicular to a principal surface of a substrate; and a switch transistor provided between the capacitive element and a bit line, turning on/off of the switch transistor being controlled based on a potential of a word line. The peripheral circuit includes a signal line that is adjacent to the lower electrode in a horizontal direction parallel to the principal surface and is supplied with a fixed potential, or a pair of signal lines respectively supplied with complementary potentials.
