Abstract
A counter circuit includes an addition circuit including counting circuits corresponding to binary bits, a subtraction circuit and control circuits. Each counting circuit obtains a carry signal and this-time bit value according to addend signal and bit value currently output by the counting circuit, outputs the carry signal to next counting circuit, and latches the this-time bit value in response to first clock and outputs same to output terminal of the counting circuit in response to second clock. The subtraction circuit is connected to the counting circuits, obtains present subtraction counting result according to present addition counting result and subtrahend signal and outputs same in response to a first refresh instruction. Each control circuit corresponds to a counting circuit, outputs, in response to second refresh instruction, corresponding bit of the present subtraction counting result to the counting circuit to serve as the bit value output by the counting circuit.
