Next generation associative memory devices for the FTK tracking processor of the ATLAS experiment

The increased energy of the interaction in ATLAS experiment need to process a lot of data\nat a high rate to generate the second level trigger. This cannot be efficiently accomplished by CPU based systems. \nDue to the high number of track to find a dedicated hardware based system perform this goal more rapidly and efficiently.\nThis system, called FTK, use associative memory to determine if data belongs to a track or not, that is \nto make pattern recognition of the particle tracks. In this paper we show the status of the art of the \nassociative memory design and their future development
