  • Method and device to control a memory
    Patent number: 5996093
    Abstract: A method and a device for determining that digital information written into a memory is correctly readable before such read information, in the form of a number of coordinated bit positions, is used to control one or several functions, where the functions can be activated by a computer unit. A selected address position or positions within the memory corresponding to the stored digital information points out a first set of bits, required to control and/or initiate the functions, and a second set of bits serving as a control sum. The second set of bits is calculated taking into consideration the current set of bits corresponding to the first set of bits and a third set of bits, corresponding to the address position currently selected for readout.
