Classification: CPC G | IPC G

Claim 12:
13. The approximate search circuit according to claim 1, wherein
each matching degree determination circuit further comprises a second detection line read circuit paired with the detection line current read circuits, and a second counting circuit,
the counting circuit counts the number of pulses transmitted through the detection lines which are generated by the data of the memory cells in the first storage circuit and signals through the activation signal input lines,
the second counting circuit former circuit counts the number of pulses transmitted through the second detection lines which are generated by the data of the memory cells in the second storage circuit and signals through the second activation signal lines, and
each of the matching degree determination circuits uses a difference between an accumulated value of the counting circuit and an accumulated value of the second counting circuit former circuit, as input values to the shift register circuit or input values to the counter circuit.
