Abstract
The device for controlling a setup/hold time of an input signal can change a setup/hold time of various control signals applied from an input buffer without physically changing the control device. The device for controlling a setup/hold time of an input signal has transmission gates for performing selectively switching operations according to a decoded test mode control signal, thereby selectively using a signal delay device in driving of drivers to appropriately control the setup/hold time of various control signals applied from a global bus line. Accordingly, the device for controlling a setup/hold time of an input signal can provide a technique which can optimize the setup/hold time at a small cost in comparison with a physical metal option control system.
