ABSTRACT:
There is a hardware implemented row copy operation mode for a DRAM to relieve the VRAMs from this slower repetitive operation. In addition, by providing circuitry that will generate a solid repetitive pattern for the full or portions of the screen. Another advantage of the invention occurs during testing of a DRAM with this circuitry. By having the ability of filling the memory array with, for example all digital ones in each cell, the quality of the die can easily be tested by modifying individual cells with a digital zero. Uniquely, this circuitry relieves the testing circuitry from filling in a background of information like the all ones background. Another feature of the invention allows graphic cards that exclusively use DRAMs, to eliminate the additional circuitry needed to perform the row copy feature, or creation of backgrounds.
