  • Method for frame memory access and display driver using the same
    Patent number: 8390637
    Abstract: The present invention relates to a method for frame memory access and a display driver using the same. The method is a data moving method for allowing a display driver integrated circuit built in a portrait style frame memory to be used in a landscape mode. The spirit of the method is to repeatedly read data from the portrait style frame memory to the shift register, and move the data on the shift register to put the data to the correct data latch to constitute complete scan line data. Therefore, the portrait style display driver integrated circuit may drive a landscape mode display panel.

  • Memory repair circuit and repairable pseudo-dual port static random access memory
    Patent number: 7808847
    Abstract: The present invention relates to a memory repair circuit and a repairable pseudo-dual port static random access memory (pseudo-dual port SRAM). The memory repair circuit uses fewer redundant column blocks and stores a few failed block addresses to reduce the required complexity of decoding the redundant column blocks. Thus, the present invention can reduce a layout area required by redundant memory cells.
