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

Claim 6:
7. 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 parallel, 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 no memory cell current and the match line voltage of the match line is kept; 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 the memory cell current and the match line voltage of the match line is discharged.
