Abstract
Semiconductor systems are provided. The semiconductor system includes a controller and a semiconductor device. The controller is suitable for generating command signals and address signals. The semiconductor device is suitable for electrically disconnecting a first local line from a second local line in response to an input control signal enabled in a read mode. The read mode is set according to a logic combination of the command signals. Further, the semiconductor device is suitable for sensing and amplifying a data on the first local line or the second local line according to the address signals to output the amplified data through an input/output line.
