Summary:
This paper presents a Ternary Content Addressable Memory with Individuality (ITCAM), which has individuality for data retrieval that is caused by the manu facturing variations of each LSI. The results of the maskable search by the ITCAM are different for each LSI. The ITCAM was implemented on three FPGA evaluation boards and tested in practice. The evaluation results showed that the data retrieval for each LSI is a little different due to the manufacturing variations and there were 179 (13%) more occupied slices, when comparing the ITCAM and conventional TCAM. Thus, the reported ITCAM is a promising solution for providing a little individual difference to each LSI.
