  • Patent number: 9692302
    Abstract: An output transistor of an output circuit that outputs a large current may have a partial fault, but such a partial fault may not be detected because the transistor is very large. To address this, the invention provides an output circuit in which one output transistor is divided into a plurality of transistors, and a plurality of pads that are connected correspondingly to the transistors are provided. Fault detection can be performed on the plurality of transistors by using each pad. At least some of the pads are connected to one same output terminal of the substrate or the like.

  • Publication number: 20170147712
    Abstract: CPUs are not effective for search processing for information on a memory. Content-addressable memories (CAMs) are effective for information searches, but it is difficult to build a large-capacity memory usable for big data using the CAMs. A large-capacity memory may be turned into an active memory having an information search capability comparable to that of a content-addressable memory (CAM) by incorporating an extremely small, single-bit-based parallel logical operation unit into a common memory. With this memory, a super fast in-memory database capable of fully parallel searches may be realized.

  • Publication number: 20160099560
    Abstract: With an IC including a driver that drives a large current, its characteristics may be deteriorated or the IC may be broken by heat generated by the large current. By providing a plurality of sensors and disposing some of the sensors so as to be close to an output driver that flows a large current, which is a source of heat generation, an increase in the temperature of the IC can be rapidly detected, and the deterioration of the characteristics of the IC can be prevented by accurately actuating an overheating protection function based on a result of detection. Alternatively, breakage of the IC can be prevented by suppressing overheating.

  • Patent number: 9154063
    Abstract: When a counter-electromotive force generated by an inductive load is applied to the drain of a switch element, the gate of the switching element may pull the gate potential toward the direction opposite to its original potential due to capacitance coupling of the drain-gate capacitance, and this may cause a malfunction. To cope with this, a switch element that pulls the potential to the reverse direction is provided and controlled to turn on at timing at which the counter-electromotive force is applied.
