  • Apparatus for transferring data from a volatile main memory to a store unit upon the occurrence of an electrical supply failure in a data processing system
    Patent number: 3959778
    Abstract: The disclosure describes improved apparatus for transferring data from the main memory of a data processor to a peripheral permanent storage unit, such as a data recording holder driven by a driving device, in response to a failure of the main electrical supply to the data processor. The apparatus includes frequency converters for supplying voltage to the processor for about 500 milliseconds after the power fails. Logic and selector circuitry reads the contents of main memory into a selected permanent storage unit within the 500 millisecond time period so that the perishable data in main memory will not be lost.
