1. A local bit-select circuit comprising:
a first set of pull-down devices comprising a first pull-down device and a second pull-down device, wherein a first source terminal of the first pull-down device is connected to a voltage supply, wherein a first drain terminal of the first pull-down device is directly connected to a second source terminal of the second pull-down device via a connection line, and wherein the connection line is distinct from a compliment read local bit line, wherein a first gate terminal of the first pull-down device is connected to a true read local bitline, and wherein the first drain terminal of the first pull-down device is disconnected from the compliment read local bit line while the second pull-down device is in an open state;
wherein a second drain terminal of the second pull-down device is connected to the compliment read local bit line, and wherein a second gate terminal of the second pull-down device is connected to a true write global bitline;
a second set of pull-down devices comprising a third pull-down device and a fourth pull-down device, wherein a third source terminal of the third pull-down device is connected to the voltage supply, wherein a third drain terminal of the third pull-down device is directly connected to a fourth source terminal of the fourth pull-down device via a connection line distinct from the true read local bit line, wherein a third gate terminal of the third pull-down device is connected to the compliment read local bitline, and wherein the third drain terminal of the third pull-down device is disconnected from the compliment read local bit line while the fourth pull-down device is in an open state; and
wherein a fourth drain terminal of the fourth pull-down device is connected to the true read local bitline, and wherein a fourth gate terminal of the fourth pull-down device is connected to a compliment write global bit line.
