Abstract
A content addressable memory device which determines the top priority entry data without assigning priorities to addresses. If ternary data stored in a cell is invalid data, and other cell at the same bit position stores valid data of entry data identical to an entry key, the entry data is determined not to be a candidate of the top priority entry data. The last entry data which has not determined not to be a candidate is determined to be the top priority data. Compared to the conventional technology which relied on the relationship between a memory address and a priority, the performance of memory system is significantly improved.
