Classification: CPC G | IPC G

Claim 10:
11. The approximate search circuit according to claim 10, wherein
each of the counting circuits is provided with a shift register circuit or a counter circuit therein, and
in the setting mode, according to the control signals from the control circuit, the shift register circuit or the counter circuit first resets its own value to a predetermined reset value, then that is made to operate to count the number of memory cells with a value “1” or a value “0” in the first storage circuit based on the number of pulse signals being passed through the detection lines by the counting circuit, and a value generated based on the counted number of the cells is written in the second memory circuit, and
in the counting mode, according to the control signals from the control circuit, a value generated based on data stored in the second-storage-circuit is first written in the shift register circuit or the counter circuit, and the counting circuit is made to operate to count in the decreasing order or the increasing order, whichever is opposite to that in the setting mode.
