Patent Number: 8,576,610

Title: Semiconductor device having floating body type transistor

Abstract: A semiconductor device is disclosed in which a signal line and a drive circuit driving the signal line in response to a signal to be transmitted are provided. A transistor of a floating body type is further provided that includes a gate, a source, a drain, and a body between the source and drain which is brought into an electrically floating state. The gate is connected to the signal line, and at least one of the source and drain is connected to a control node that is supplied with a control signal. The control signal is configured to receive a control signal that changes from the first level to a second level during the period of time when the drive circuit is driving the signal node.
