摘要
A content addressable memory (CAM) cell includes a first storage element for storing a data value, a second storage element for storing the data value, and a compare circuit having first inputs to receive from the first storage element a first complementary data signal indicative of the data value, second inputs to receive from the second storage element a second complementary data signal indicative of the data value, third inputs to receive comparand data, and an output coupled to a match line. The CAM cell allows for simultaneous read and compare operations, as well as simultaneous refresh and compare operations.
