Abstract: A sense amplifier circuit includes a first voltage-controlled current source to supply current proportional to a first bias voltage to a reference node and a second voltage-controlled current source to supply current proportional to a second bias voltage to a sensing node. The first and second bias voltages are internally generated in response to an externally applied sense amp control signal. A current mirror circuit is also provided for the sense amplifier circuit. The current mirror circuit commonly deliver current proportional to the voltage level of the reference node to the reference and sensing nodes. A differential amplifier amplifies a difference voltage between reference and sensing nodes. This current mirror type sense amplifier circuit allows data sensing operation to be performed without being influenced from the external conditions and without sensing speed loss due to the instability of the precharge current since the voltage-controlled current sources are controlled by the internal bias voltages.

Abstract: A method and apparatus for generating a three-dimensional FEM are provided. In the three-dimensional FEM generating method, a surface mesh is generated by meshing the surface of a three-dimensional model of a three-dimensional object. A projected contour is generated by projecting the three-dimensional model from one direction, and a projected contour mesh is generated by meshing the surface of the projected contour. A solid base mesh is generated by stacking solid elements on a base side formed of two-dimensional elements of the projected contour mesh. The surface mesh is substituted into the solid base mesh in alignment with the projected contour. A final solid mesh is generated by distinguishing solid elements surrounded by the surface mesh in the solid base mesh.
