TowerJazz and Crocus Debut MRAM TechnologyJuly 18, 2013
The magnetic memory implementation offers SRAM performance in terms of speed and power with nonvolatile memory capabilities.
SANTA CLARA, CA & MIGDAL HAEMEK, Israel /BUSINESS WIRE/ -- Tower Semiconductor Ltd., a global specialty foundry leader, and Crocus Technology, a leading provider of magnetically enhanced semiconductors, announced a major breakthrough in a disruptive magnetic technology that has been co-developed with Crocus Technology. The technology now offers SRAM performance in terms of speed and power with nonvolatile memory (NVM) capabilities. This magnetic random access memory (MRAM) solution has demonstrated best-in-class performance and more than 2 billion cycles of program/erase were demonstrated on a 4 Mb NVM product. The first market to be addressed is battery-backed SRAM (BB-SRAM). Crocus' product provides the best characteristics of current BB-SRAM offerings—fast access times, low power, and unlimited write cycles—without the need for cost, recharging, and long-term disposal of a lithium battery.
According to a 2013 "Emerging Non-Volatile Memories" report from Yole Developpement, higher-density NVM chips will spawn many new applications and increase the business 10-fold in just five years. According to the report, the sizable growth in emerging NVM will be due to increased use in various markets, including: industrial and transportation, enterprise storage, smart card, mobiles phones, and mass storage.
Crocus has developed a robust, reliable, and scalable MRAM process; its Magnetic Logic Unit (MLU) architecture is based on its patented, revolutionary self-reference Thermally Assisted Switching technology, which enables a number of previously unachievable breakthroughs in magnetic memory implementation. These include highly robust, secure embedded memory, ultra-high-temperature NVM operation (e.g., >200°C), order-of-magnitude higher density hardware-based table searches (e.g., content addressable memory), high-density multi-bit storage, and scaling to sub-20 nm manufacturing.
"Crocus and TowerJazz have collaborated for many years to develop this disruptive technology to address the growing and vast number of markets that can be served by emerging NVM, such as cache memory for enterprise storage, MCUs for smart cards, industrial and automotive applications, mobile phones, and more," said Bertrand F. Cambou, Executive Chairman of Crocus Technology. "TowerJazz is a known leader in NVM foundry solutions and has been the ideal partner to quickly bring leading-edge commercial chip products to an eager and growing marketplace. Our collaboration will enable us to achieve high-volume business for both companies, with a long life on TowerJazz's platform."
"We are excited to bring this technology to volume production in Q4 this year, and in so doing to be the first foundry with MRAM capability. At 2 billion program/erase cycles with 1 billion read at less than 35 nsec on a 4 Mb product, this technology outperforms any other available MRAM solution in the market," said Russell Ellwanger, CEO TowerJazz. "We have a long history and much expertise with NVM at TowerJazz, having co-developed the initial Saifun NROM technology, as well as organically holding strong NVM IP blocks, such as Y-flash, a zero-mask adder mid-size NVM. The Y-Flash is a powerful enabler in volume production with many of our customers and has been licensed to the largest in our industry. With this background, our team is qualified and realistic to state that the MRAM activity and the achievements with Bertrand and his Crocus team are revolutionary and offer innovative solutions to a number of our respective customers."
Crocus' proprietary MRAM technology solves all the known problems encountered in earlier MRAM developments. The company's technology has demonstrated its stability, reliability, data retention, endurance, and scalability, while exhibiting high speed, low power dissipation, and excellent resistance to external perturbation.
MRAM's unique characteristics make it particularly suitable to a wide variety of telecommunication, networking, computing and handheld applications currently using SRAM and/or flash memory technology. It is the only proven new memory technology providing non-volatility, unlimited-write-endurance, high-density, and symmetrical high-speed read & write. It is particularly well-suited to applications requiring high data reliability and high performance, and has the unique potential of becoming the universal embedded memory technology for systems-on-chip devices.
Crocus Technology is a leading developer of a magnetically enhanced semiconductor technology for mobile security, embedded microcontrollers, and applications requiring extreme operating conditions. Crocus' breakthrough proprietary MLU technology offers many advantages for applications demanding high-speed, secure, and robust performance at lower cost. In embedded security, Crocus' tamper-resistant MLUs read and write faster than flash memory and fit in a smaller footprint. Available in SIM and other embedded form factors, MLUs bring unprecedented levels of secure authentication for mobile payments, access control, and other critical data transactions needing high-level security. In the embedded space Crocus' MLUs are effective in replacing most existing memory blocks with the added ability of operating in rugged environments, notably in high-temperature electronics (400°C). Founded in 2004, Crocus is led by a senior management team with high-level industry experience from Motorola, AMD, Intel, and Gemalto. It has U.S. operations in Santa Clara, CA, and offices in Grenoble and Gardanne, France.
