Abstract
An associative memory device has associative memory cells arranged in matrix and each implemented by a parallel combination of two electrically erasable and programmable non-volatile memory transistors, and a multi-bit data code stored in a row of associative memory cells allows the two electrically erasable and programmable non-volatile memory transistors of each associative memory cell to selectively enter the programmed state so that a multi-bit key code is checked to see whether or not drain current flows through the electrically erasable and programmable non-volatile memory transistors into a source line.
