Contemporaneously, for each of the words: a first checksum is calculated on the binary digits; and the following are stored in a corresponding portion of a RAM: an identifier of the binary digits and the first checksum. The ternary content-addressable memory is queried with an input word. Upon the querying yielding a match, further steps include retrieving, from the random-access memory, corresponding values of the identifier of the binary digits and the first checksum; computing a second checksum on the input word, using the identifier of the binary digits; and if the second and first checksums are not equal, determining in real time that the match is a false positive."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Concurrent error detection in a ternary content-addressable memory (TCAM) device","description":"A plurality of data words are written into a TCAM; each has binary digits and don't-care digits.
