  • Patent number: 7813196
    Abstract: An integrated semiconductor memory contains a multiplicity of bit line pairs which each comprise a first bit line and a second bit line. Sense amplifiers are each coupled to one of the bit line pairs for evaluating a signal on the first and second bit lines. A data line pair coupled to at least one of the multiplicity of bit line pairs for outputting a datum is furthermore provided. A correction device is connected on the output side to the data line pair or to at least one bit line pair. The device is embodied for feeding a correction signal onto the line pair.

  • Publication number: 20050180625
    Abstract: Disclosed is an image segmenting device provided with a plurality of pixel pulsed artificial neurons which are coupled to each other via one respective weighted coupling. A weight-modifying unit modifies the weights of the couplings according to the pulse signals of the neurons such that neurons of a segment that is to be formed emit neuron pulse signals in an increasingly synchronous manner.
