Single ended sense amplifier
The present invention is related to a single ended sense amplifier, which is engaged in receiving signals of a memory apparatus of a semiconductor, and generates output signals in an output terminal. The single ended sense amplifier comprises: a first loading unit, which offers a loading current; a first sense switch unit, which is in between a memory apparatus of semiconductor and the first loading unit to couple them together, and connects to the first loading unit to form an output terminal in order to be as a channel switch for a channel from semiconductor memory apparatus to the output terminal of the sense amplifier; a second loading unit, which offers a charging current; a second sense switch unit, which is in between the semiconductor memory apparatus and the second loading unit to couple them together; an inverse logic unit, which is among the semiconductor memory apparatus, the first sense switch unit and the second sense switch unit for controlling the plural sense switch units. Hence, The second sense switch unit is capable to control the charging current to improve the reaction speed of the sense amplifier without pre-charging control signals.
