  • Semiconductor integrated circuit device
    Patent number: 7612604
    Abstract: A body bias control system allows for independent design of a functional module, thereby reducing the burden of designing the module. The body bias control system provides a switch circuit having an area in which the body bias is controlled independently of its outside portion, for controlling the supply of body bias in the vicinity of the area. Preferably three types of switches are provided for switching the body bias to suitable levels for a standby mode, a mode of normal operation and a mode of high-speed operation.
    Type: Grant
    Filed: May 6, 2003
    Date of Patent: November 3, 2009
    Assignees: Hitachi, Ltd., Hitachi ULSI Systems Co., Ltd.
    Inventors: Masayuki Miyazaki, Yusuke Kanno, Goichi Ono, Toshinobu Shinbo, Yoshihiko Yasu, Kazumasa Yanagisawa, Takashi Kuraishi
