A method and apparatus includes row-major memory mapping for a graphics memory (14) while providing data to a column-major display such as a pixel array (19). The transfer of data is provided from a row-major memory map to data formatted for refreshing a column-major display. The column-major pixel array (19) provides a display with energy saving benefits for illuminating the LEDs. A software developer can provide graphics data generated or transferred by a microcontroller (12) for storage in the row-major graphics memory (14). The embodiment supports the display features such as the grey-scale mode and bi-level mode.

LED display controller and method of operation

A system and method for aligning a semiconductor device (10) to a fixture (11) is provided. A first physical alignment feature (12) on the semiconductor device (10) and a second physical alignment (24) on the fixture (11) mate to align and hold the semiconductor device (10) in place. In one embodiment the physical alignment features (12) and (24) are produced using standard photolithography techniques, resulting in precise alignment features. In another embodiment the physical alignment features (12) and (24) are designed and placed to control the direction the thermal expansion of the semiconductor device (10) relative to the fixture (11).
