Abstract
The present invention relates to a precharge/discharge nonvolatile memory circuit for detecting signals output from two bit lines on read-cell and dummy cell sides using a flip-flop circuit, comprising a first row decoder on the read-cell side, a second row decoder on the dummy-cell side, a first column decoder on the read-cell side, a second column decoder on the dummy-cell side, a read cell selected by the first row decoder and the first column decoder, a dummy cell selected by the second row decoder and the second column decoder, first and second precharge transistors for performing a precharge operation, first and second discharge transistors for performing a discharge operation, the flip-flop circuit, a discharge control circuit for generating a discharge signal, and a precharge control circuit for generating a precharge signal after the discharge signal is generated from the discharge control circuit.
