    Abstract: A semiconductor device includes a substrate, first and second isolation layers, an insulation layer pattern, and a gate structure. The substrate has a cell region and a peripheral region. The first isolation layer is buried in a first upper portion of the substrate in the peripheral region. The second isolation layer is buried in a second upper portion of the substrate in the cell region, and extends along a first direction substantially parallel to a top surface of the substrate. The insulation layer pattern is buried in the first upper portion, and extends along a second direction substantially parallel to the top surface of the substrate and substantially perpendicular to the first direction. The insulation layer pattern has a lower surface higher than a lower surface of the second isolation layer, and applies a stress to a portion of the substrate adjacent thereto.

    Abstract: A resistive memory device includes a memory cell array having a plurality of memory cells therein, which operate in response to word line driving and column selecting signals. Each of memory cells includes a resistive device and a cell transistor connected in series. An I/O sense amplifier senses and amplifies data output from the memory cell array to thereby generate output data, and also generate program current based on input data and provide the program current to the memory cell array. The resistive memory device is also configured to read output data from the I/O sense amplifier and adjust interface states of the cell transistors based on a voltage level of the output data during a test mode.
