Abstract
A first write transistor has a source connected to a power-supply node, a drain connected to a first local bit line, and a gate connected to a second write global bit line. A second write transistor has a source connected to the power-supply node, a drain connected to a second local bit line, and a gate connected to a first write global bit line. A third write transistor has a source connected to the first write global bit line, a drain connected to the first local bit line, and a gate receiving a first control signal. A fourth write transistor has a source connected to the second write global bit line, a drain connected to the second local bit line, and a gate receiving the first control signal. A read circuit is connected to the first and second local bit lines and first and second read global bit lines.
