1. A semiconductor device comprising:

  • a word line;

    a first bit line and a second bit line;

    a first memory cell electrically connected to the word line and the first bit line;

    a second memory cell electrically connected to the word line and the second bit line;

    a first switching element including a first terminal electrically connected to the first bit line;

    a second switching element including a first terminal electrically connected to the second bit line;

    a first precharge circuit configured to output a precharge potential to the first bit line, wherein the first precharge circuit is electrically connected to the first bit line through the first switching element;

    a second precharge circuit configured to output a precharge potential to the second bit line, wherein the second precharge circuit is electrically connected to the second bit line through the second switching element; and

    a circuit configured to operate the first switching element and the second switching element selectively.
