Business Characteristics

Energy-efficient and high-performance AI semiconductor chips for edge inference

  • High-performance, energy-efficient AI chip using in-memory computing (analog-PIM)

    - Develops advanced PIM core technology and multicore neural networks
    - Achieves high performance and low power consumption with in-memory computation without data movement

  • Optimized for edge AI with neuromorphic architecture + high reliability

    - Reliable neuromorphic AI with analog computing and NOR flash architecture

Case Studies

Case 1

AI breaker

  • Prototype smart breaker conforming to Japanese specifications (electric current/voltage) with the capability to detect and interrupt arc fault signals

    Objective: To achieve automatic shutdown through arc detection for devices with fire risks, such as electric heaters and microwave ovens.

  • Configuration: Current sensor / Arc detection circuit / AI inference chip / Power shutdown relay

  • Items for verification: Typical small appliances (e.g., electric kettles, hair dryers)

  • Note: Ensures privacy and responsiveness through on-device AI processing without the need for a network connection.

Case 2

Smart lamp

  • A smart light with added voice recognition functionality that allows it to be turned on and off using voice commands

    Purpose: Enhances usability during disasters and in dark environments and improves convenience for everyday use.

  • Configuration: Pre-assembled night light + microcontroller + microphone + voice recognition AI chip

  • Operating conditions: Can be used if a company can record and provide audio data.

  • Note: No Wi-Fi required, achieving both simplified implementation and cost reduction through on-device voice processing.
