OPERATION METHOD OF SEMICONDUCTOR DEVICE

摘要

PURPOSE: An operation method of a semiconductor device is provided to reduce the number of operation voltage of a semiconductor device by uniformly maintaining a voltage level of a source voltage. CONSTITUTION: A semiconductor device includes a drain region(150), a source region, a floating body region, and a gate region. Common source lines are commonly connected to source regions(140) of at least two semiconductor devices among a plurality of semiconductor devices. A drain voltage pulse is transited from an enable state to a standby state. A gate voltage pulse is transited from the enable state to the standby state. A drain voltage pulse is transited from the enable state to the standby state. Carriers saved in the body region(170) are removed.
