Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 10:
11. An analog content addressable memory (CAM) cell including:
a first memory cell and a second memory cell coupled to each other,
wherein
the analog CAM cell stores analog storage data;
the analog storage data of the analog CAM cell is corresponding to a match range, the match range is determined based on a first threshold voltage and a second threshold voltage of the first memory cell and the second memory cell;
an analog search data is converted into a first analog search voltage and a second analog search voltage;
the first memory cell and the second memory cell receive the first analog search voltage and the second analog search voltage; and
the analog CAM memory cell generates a memory cell current, or the analog CAM memory cell keeps or discharges a match line voltage on a match line coupled to the analog CAM memory cell,
the analog CAM cell is further coupled to a sensing amplifier, and the match range of the analog CAM cell is adjusted by adjusting a current sensing level of the sensing amplifier.
