ABSTRACT:
Disclosed is a single-ended bit line structure of latched type, capable of sensing data at a high speed. The present invention decreasing the power consumption, by selectively separating the single-ended sense amplifier from the bit line and the reference voltage generator through the PMOS transistors at the same time the sensing operation starts. The single-ended bit line structure according to the present invention includes a reference voltage generator for generating a constant voltage, a latched-type sense amplifier and a switching unit for separating the latched-type sense amplifier from the reference voltage generator and a bit line at the same time the latched-type sense amplifier is enabled.
