Patent Number: 6,310,880

Title: Content addressable memory cells and systems and devices using the same

Abstract: A content addressable memory cell 920 includes a first storage element 922a for storing information and a first transistor 921a for selectively transferring charge representing information from a first bitline 924a to the first storage element 922a. A second transistor 921b selectively transfers charge representing information from a second bitline 924b to a second storage element 922b. First and second comparelines 925a, 925b carry first and second bits of a comparand to a comparator 905, 906, 908 which compares the first and second bits of the comparand with information stored on the first and second storage elements. In response, comparator 905, 906, 908 selectively controls a voltage on a corresponding one of a plurality of matchline 909.
