Latest Patents

Mullauer holds a patent for a "Method and apparatus for testing integrated circuit memories." This invention includes a random sequencer circuit that generates a pseudo-random data bit pattern to be written into the cells of a DRAM chip. The apparatus features a variable clock circuit that produces a continuously variable frequency clock signal, allowing for the continuous increase in the speed at which data is written into the DRAM. During the read cycles, the data read from the DRAM is compared with the generated pattern, and any discrepancies activate an LED to indicate a chip failure. This innovative method allows for the determination of the maximum speed of the chip, effectively isolating defective and marginally damaged chips. The apparatus operates as a stand-alone unit, eliminating the need for software or an interfaced host microprocessor.
