Latest Patents

One of Iketani's latest patents is a semiconductor integrated circuit device that operates stably at multiple power supply voltage levels. This invention features MOS transistors that are alternately rendered conductive as current source transistors at the last stage of a level converter. These transistors are selectively activated based on the voltage level of a bonding pad, allowing for adjustable charging and discharging currents towards the internal node. This innovation ensures that the rising and falling times of the internal signal remain equal, enabling the input/output circuit to provide signals at the correct timing, even when the system power supply voltage fluctuates.

Another notable patent is a semiconductor device that allows for the external identification of set functions. This device includes a checking circuit that connects a pad to a reference potential source node based on the potential of a special pad when activated. This checking circuit is triggered by a burn-in mode detection signal. By detecting the leak current of a pin terminal connected to the circuit, the potential of the special pad can be identified externally. This feature allows for the non-destructive detection of bonding options based on the potential of the bonding pad.
