Patent abstract
A content addressable memory (CAM) device (200) can equalize a potential between a match line (202) and corresponding pseudo-supply (PVSS) line (204) in a pre-sense operation. In a sense operation, a sensing device (P4) can determine a match condition exists when the match line (202) potential varies from the PVSS line (204) potential. Complementary compare data lines (CD and BCD) can be equalized with one another in a pre-sense operation, while one compare data line (CD or BCD) can be equalized with bit lines (BB1 and/or BB2) in the sensing operation.
