  • Patent number: 9558114
    Abstract: The disclosure relates to an electronic memory system, and more specifically, to a system for storing data in an adjustably partitionable memory array, and a method to store data in an adjustably partitionable memory array. According to an embodiment of the disclosure, a system to store data in an adjustably partitionable memory array is provided, the system including a plurality of memory cells arranged in an array of rows and columns, a plurality of bit lines, and a plurality of switches, wherein each bit line is electrically coupled to a column of memory cells and each bit line comprises a switch configured to allow the respective bit line to be partitioned by opening of the switch.
    Type: Grant

  • Patent number: 4987500
    Abstract: The present invention utilizes a dual frequency data writing scheme. At a first frequency, flux transitions are achieved which result in large excursions of the information signal. In the preferred embodiment, the first frequency approximates the maximum frequency at which such excursions can occur. A second higher frequency is utilized to create the very small or no excursions. At this second higher frequency, a complex flux transition is not achieved. Therefore, there is little or no information signal. Information is represented by the presence or absence of excursions. In the preferred embodiment, the first frequency is approximately 33,000 flux changes per inch, and the second frequency is approximately 67,000 flux changes per inch. In order to detect data written by the present scheme, an adaptive, self-compensating scheme is utilized. The present invention utilizes an excursion detection scheme which is pattern and radii independent.
