Bitline sense amplifiers and semiconductor devices including the same

Abstract

A bitline sense amplifier comprising: a P-type sense amplifier including a first PMOS transistor and a second PMOS transistor, wherein the first PMOS transistor and the second PMOS transistor are electrically connected to a first sense enable line; an N-type sense amplifier including a first NMOS transistor and a second NMOS transistor, wherein the first NMOS transistor and the second NMOS transistor are electrically connected to a second sense enable line; a first isolation transistor electrically connected to the first PMOS transistor and to the first NMOS transistor; a second isolation transistor electrically connected to the second PMOS transistor and to the second NMOS transistor; a first transistor electrically connected to a first node that is between the first PMOS transistor and the first isolation transistor; and a second transistor electrically connected to a second node that is between the second PMOS transistor and the second isolation transistor.
