| 20100226193 | SEMICONDUCTOR MEMORY DEVICE - A unit memory circuit includes a fuse element capable of electrically programming data. A sense amplifier circuit is connected to the fuse element. The sense amplifier circuit senses data of the fuse element. Either of a first interconnect and a second interconnect is selectively formed by changing an interconnect formation mask. The first interconnect is short-circuiting the fuse element and the second interconnect is cutting off a current path when data is read from the fuse element. | 09-09-2010 |

| 20080225051 | METHOD AND APPARATUS FOR THREE-DIMENSIONAL GRAPHICS, AND COMPUTER PRODUCT - A graphic apparatus that draws an object three-dimensionally using a level plane and a height-axis perpendicular to the level plane includes a receiving unit, a calculating unit, and a drawing unit. The receiving unit receives vertex data identifying a position of a top surface of the object on the level plane. The calculating unit calculates a modulation coefficient of luminance for the top surface based on a normal vector for the top surface and a light-source vector indicating a direction of a light source on the level plane. The drawing unit draws the top surface using the vertex data and the modulation coefficient, and a top surface of another object using the modulation coefficient. | 09-18-2008 |
| 20090073180 | GRAPHICS DRAWING APPARATUS, METHOD, AND PROGRAM AND RECORDING MEDIUM ON WHICH THE PROGRAM IS RECORDED - A graphics drawing apparatus drawing a graphic, including: a generation unit, where a sequence of two-dimensional coordinates of vertices is input, generating the coordinates of each of the vertices and virtual vertex coordinates for the coordinates of each of the vertices on a memory, the virtual vertex coordinates being generated by converting the X-coordinate value of the coordinates of each of the vertices to the X-coordinate value of the coordinates of the leading vertex of the sequence; and a setting unit that sets the coordinates of two vertices of a partial graphic that is to be created as the coordinates of two adjacent vertices, in sequence starting from the leading vertex, and, after setting the coordinates of the trailing vertex of the sequence, setting the coordinates of two vertices of the partial graphic that is to be created as the coordinates of the leading and trailing vertices. | 03-19-2009 |
| 20090303240 | GRAPHICS SYSTEM AND DRAWING METHOD THEREOF - A graphics system including: a register storing data of a clipping frame of a frame buffer; a register storing offset data of a figure; a register storing data of a clipping frame of a stencil buffer that is larger than the clipping frame of the frame buffer and storing position data of a reference basing point, on a stencil buffer, for drawing a non-offset figure or an offset figure; and a pixel filling-in module for drawing onto a stencil buffer a masking determination result of a pixel relating to the figure on the basis of data of the clipping frame of the stencil buffer and the figure, and also drawing the non-offset figure or the offset figure onto the frame buffer by referring to the stencil buffer onto which the masking determination result is drawn, the position data of a reference basing point stored in the register, and the data of the clipping frame of the frame buffer. | 12-10-2009 |
