Abstract
A semiconductor memory device includes linear patterns disposed between isolation trenches extending in a first direction in a semiconductor device and having a first crystal direction the same as the semiconductor substrate. A bridge pattern connects at least two adjacent linear patterns and includes a semiconductor material having a second crystal direction different from the first crystal direction. A first isolation layer pattern is disposed in at least one of the isolation trenches in a field region of the semiconductor substrate. Memory cells are disposed on at least one of the linear patterns.
