Toggle MRAM Technology from Everspin Technologies is a memory solution that melds non-volatility with the high-speed performance of RAM, enabling devices to have an "always-on" capability. This MRAM utilizes a single transistor and a magnetic tunnel junction (MTJ) to ensure high-density storage with excellent reliability and long-term data retention of up to 20 years even under significant thermal stress. This technology is designed to blend seamlessly into existing systems, delivering the speed of SRAM with the durability of non-volatile Flash memory in a single module. Its architecture fortifies data against power interruptions by automatically safeguarding it during voltage dips, making it ideal for essential applications across various sectors. The architecture of Toggle MRAM involves the use of magnetism in electrons to store information, which eliminates the typical wear-out associated with electrical charge memory. The magnetic properties grant it swift read/write capability, combined with robustness and longevity, making it particularly suitable for use in industrial IoT and other demanding environments. This MRAM uses a unique design consisting of a fixed magnetic layer opposite to a free one, separated by a thin dielectric, which helps maintain consistent data integrity. Toggle MRAM is especially advantageous in scenarios where data reliability and quick access times are critical, such as in industrial automation, telecommunications, and aerospace technologies. Its resistance-based read mechanism ensures efficient data retrieval, while its magnetic field writing technique enhances its performance by targeting specific memory locations without disturbing surrounding data. This makes it highly scalable and adaptable for various technological needs, thereby positioning it as a dynamically integrative component in modern architectures.
Everspin's Parallel Interface MRAM is designed to offer a combination of high-speed performance and robust data storage capabilities. Compatible with SRAM, this MRAM supports both 8-bit and 16-bit parallel interfaces, providing data access times of 35 to 45 nanoseconds and handling an endurance beyond conventional limitations. The MRAM architecture ensures data persistence, protecting information against power failure scenarios via integrated low-voltage inhibit circuits that suspend writing operations if voltages go beyond specification limits. Available in multiple configurations ranging from 256Kb to 32Mb, the Parallel Interface MRAM is engineered to meet the demands of various applications needing fast data access and retention, especially in environments where data integrity is paramount. Its comprehensive support for a range of supply voltages (typically around 3.3 volts) and flexible timing specifications allow it to be integrated into diverse system architectures efficiently, catering to the needs of industries like automotive, aerospace, and data-driven infrastructure. This MRAM variant is particularly beneficial for systems that require dependable performance in less-than-ideal conditions — including high-frequency data logging in avionics and harsh automotive environments. The MRAM's quick response times and resistance to electrical fluctuations make it indispensable in maximizing operational reliability, helping to streamline system designs by removing the necessity of additional energy storage or backup components traditionally associated with data safeguarding.
The Serial Peripheral Interface (SPI) MRAM from Everspin features rapid data transfer using a minimalistic pin configuration, optimized for efficient use in space-constrained applications. This MRAM is engineered for applications where quick storage and retrieval are critical, such as in advanced RAID controllers and state-of-the-art server system logs. It operates with speed and efficiency, delivering data transfer rates up to 52MB/s using a quad SPI configuration, surpassing traditional parallel interfaces in performance and flexibility. The MR10Q010, Quad SPI MRAM, epitomizes high-speed access facilitated by a 16-pin small-form-factor package, making it an excellent choice for embedded systems and storage buffers where space and power efficiency are of paramount importance. Its ability to function under a 3.3V power supply, with an adaptive 1.8V I/O operation, underscores its versatility across different system voltages and configurations, making it a go-to solution for next-generation electronics. This versatile MRAM's suitability spans various realms, providing reliable data storage and quick access in systems requiring intense data throughput under constraints of space and energy. It is tailored for applications where the impact of non-volatility and low latency can substantially elevate system performance, thereby serving crucial roles in embedded computing, storage applications, and flexible data solutions across platforms.
