  • Associative memory and method for the operation thereof
    Patent number: 6160729
    Abstract: An associative memory contains cells that are formed of a series circuit of an ordinary PMOS transistor with a PMOS transistor with a floating gate. The ordinary PMOS transistor receives of an input vector and the gate of the second PMOS transistor is connected to a learning input. For the associative access, a second vector can be applied to the drain terminal of the second PMOS transistor and, upon readout, the current flow through the respective series circuit is evaluated column-by-column by current evaluator circuits.
