  • Toshiba Develops New Chip Authentication Technology Using Transistor Noise (Jun. 2015) Toshiba has developed a novel method of utilizing random telegraph noise (RTN) originating from insulating material faults to implement a physical unclonable function (PUF), an important security technology that has attracted considerable attention in recent years. The method, which will contribute to the creation of safe and secure cloud services for smart communities, was announced at the VLSI Technology Symposium, an international conference on semiconductor devices to be held on June 16 in Kyoto, Japan.

  • Toshiba and Landis+Gyr Make Proposal on IEEE 802.21d Standardization for Security of Multicast Communications (Apr. 2015) Toshiba Corporation and Landis+Gyr have jointly proposed to the IEEE (The Institute of Electrical and Electronics Engineers, Inc.) 802.21d Task Group a draft technical document for standardization of group key management systems and public key certificate management systems, and the sponsor voting for which has been completed. Once approved by the IEEE Standards Association, the proposal will be established in the form of standards and norms.

  • Development of a nonvolatile memory circuit for high-performance processors using new types of magnetic memory elements (Mar. 2015) We have developed a spin-transfer torque magnetoresistive random-access memory (STT-MRAM) circuit for use in high-performance processors and system-on-a-chip (SoC) integrated circuits, implementing a 1-Mb class of new magnetic materials. The newly developed memory circuit allows low-power, high-efficiency, high-speed performance in energy-efficient magnetic tunnel junction (MTJ) memory.
    The proposed memory circuit provides speed performance capable of 3.3-ns access to in-cache memory. The circuit furthermore consumes approximately 80% less power than conventional static RAM (SRAM) as embedded memory, giving it the best power performance of any type of embedded memory. Details of the proposed technology will be presented on February 24 at the 2015 International Solid-state Circuits Conference in San Francisco.

  • Development of a Cloud System for Instantaneous Remote Control of over One Million Devices on the Internet of Things (Jan. 2015) Toshiba has developed a cloud system for instantaneous remote control of over one million devices on the Internet of Things (IoT). In the IoT world, in which diverse devices, such as home devices and sensors, are connected to the Internet, multiple control command relay servers are necessary with a scale of over one million devices. We developed a system that can connect more than 100,000 devices using a server instance that is not high performance (equivalent to a regular laptop computer with 4 GB of memory). Furthermore, a low-latency communication is maintained by always connecting the controlling mobile terminal and the controlled home device to the same server. The system also dynamically increases or decreases the number of servers depending on the number of connected devices. This technology was unveiled at IEEE CCNC 2015(Note 1) that was held from January 9 to 12.
