Classification: CPC G | IPC G

Claim 7:
8. The data searching and comparing method for the analog CAM device according to claim 6, wherein
the analog CAM cell includes a first and a second memory cells coupled in serial, the first and the second memory cells having the first threshold voltage and the second threshold voltage, respectively;
the first and the second memory cells receive the first analog search voltage and the second analog search voltage;
the first and the second memory cells are coupled to the match line;
when the first analog search voltage and the second analog search voltage match with the match range, the analog CAM cell generates the memory cell current; and
when the first analog search voltage and the second analog search voltage does not match with the match range, the analog CAM cell generates no memory cell current.
