MRAM (Magnetoresistive Random Access Memory) is a type of non-volatile memory that uses magnetic fields to store data. Unlike traditional RAM, MRAM does not require power to retain data, meaning that data can be stored even when the power is turned off. This makes MRAM a good choice for applications that need to store large amounts of data while being power-efficient.
MRAM SSDs (Solid State Drives) are storage devices that use MRAM as the main memory. They offer many advantages over traditional hard drives, such as faster data transfer speeds, higher reliability, lower power consumption, and longer lifespan.
MRAM SSDs are becoming increasingly popular for a variety of applications, from consumer electronics to industrial applications, due to their fast read and write speeds. Additionally, MRAM SSDs are resistant to shock, vibration, and temperature changes. This makes them ideal for use in harsh environments.
MRAM SSDs offer a number of advantages over traditional hard drives, such as higher data transfer rates and higher reliability. Additionally, MRAM SSDs are more energy efficient, since they don’t need to spin up or down to access data. This makes them a great choice for laptop computers, which need to be highly energy efficient.
MRAM SSDs are available in a range of capacities, from small form factors such as mSATA and M.2 to larger 2.5-inch and 3.5-inch form factors. This makes them suitable for a variety of applications, from consumer electronics to industrial applications.
Overall, MRAM SSDs offer many advantages over traditional hard drives. They are faster, more reliable, more energy efficient, and more resistant to shock, vibration, and temperature changes. This makes them a great choice for many applications, from consumer electronics to industrial applications.
The Global MRAM SSD market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Storage accelerator market-focused MRAM SSDs have been introduced by Everspin.MRAM has far lower storage density than NAND flash, but it is also much more reliable and should operate faster than NAND memory.
Chips from Everspin are the densest, with 256Mb per die. That is not that big when compared to even planar NAND, and flash densities have skyrocketed since the introduction of 3D NAND.
The nvNitro brand will be used to market Everspin’s new SSDs, which will come in 1GB and 2GB capacity and ship within a new window. Designed to accelerate storage operations rather than be utilised as bootable operating systems, these tiny drives provide IOPS with “six microsecond end-to-end latency,” according to Everspin.
It is possible to map them as memory-mapped I/O or as NVMe SSDs. Though it’s debatable how much of an effect this will have on cost, the endurance of MRAM eliminates the need for complex controller methods to implement wear levelling or write combining. Everspin states in one section of its press release that it will launch 4GB to 16GB capacities this year, but in another, it talks about “capacity options ranging from 512MB to 8GB throughout the year.
” Regardless, it is evident that the company is ramping towards the larger capacity that could enable it to establish a name for itself in the storage sector. IBM Offers 19-Tb SSD With Data Cache Made of Everspin MRAM.
They sometimes come with baggage that keeps them from addressing a larger space, but they also frequently offer ancillary benefits that make them appealing for select, niche uses. Supercapacitors and specially designed drive enclosures have been employed by IBM’s FlashSystem in the past to backup a DRAM write cache.
The supercapacitors maintain the system’s power after a power outage for long enough to complete writing DRAM data back to the NAND cache. Switching to 2.5-inch U.2 drives for IBM’s new system required developing a new technique for system level power protection. This is the role of MRAM.
A non-volatile memory technique called Spin-Torque MRAM (ST-MRAM) combines the advantages of solid-state memory and conventional magnetic storage.
With benefits including high-speed operation, non-volatility, and exceptional endurance, it presents an appealing alternative to current memory technologies like DRAM (Dynamic Random-Access Memory) and NAND Flash.
Spin-transfer torque, which involves modifying the spin of electrons to store and retrieve data, is the basis for how ST-MRAM functions. It makes use of a magnetic tunnel junction (MTJ) structure, which is composed of two magnetic layers and a thin insulating layer between them. Both parallel and anti-parallel magnetic orientations can be found in these magnetic layers.
By passing current through the MTJ structure, which causes the electron spins to align either parallel or anti-parallel, ST-MRAM is able to store data. There are two unique resistance states that correspond to the binary values 0 and 1, depending on how the magnetic layers are aligned relative to one another.
The quick read and write speeds of ST-MRAM are one of its key benefits. For high-performance applications, it can offer access times that are comparable to or even faster than SRAM (Static Random-Access Memory). Low-latency operations are made possible by ST-MRAM since it doesn’t need time-consuming erase and write cycles like other non-volatile memory like NAND Flash do.
The non-volatility of ST-MRAM is another important characteristic. Similar to Flash memory, it maintains data even after the power source is shut off. Due to this feature, it is appropriate for applications including storage devices, industrial automation, and automotive electronics that require instant-on capabilities and data persistence.
Additionally, ST-MRAM has exceptional endurance, meaning it can withstand numerous read and write cycles without degrading. This characteristic makes it ideal for applications where endurance is crucial, such as those that receive frequent data updates.
The scalability of ST-MRAM allows for the creation of high-density memory arrays. Higher storage densities are possible by scaling down the size of the MTJ structures. This scalability makes ST-MRAM a strong contender for upcoming memory technologies, along with non-volatility, high-speed operation, and scalability.
Several businesses are working hard to develop and commercialize ST-MRAM solutions. For instance, Everspin Technologies is a well-known producer of ST-MRAM components. They provide a variety of embedded solutions and discrete ST-MRAM chips aimed at different applications.
In the ST-MRAM market, Spin Memory (formerly Spin Transfer Technologies) is a key competitor. They concentrate on creating ST-MRAM solutions for IoT, computing, and storage applications. Both standalone memory chips and embedded solutions are available from them.
Because ST-MRAM has the potential to overcome the drawbacks of current memory technologies, it has attracted interest recently. Speed, non-volatility, endurance, and scalability are all enticing combinations that it offers.
Data centers, edge computing, artificial intelligence, and Internet of Things (IoT) devices are just a few of the industries where the technology is projected to find use as it develops.
The promise of high-performance, non-volatile, and dependable memory solutions for diverse applications makes ST-MRAM an exciting leap in memory technology overall. ST-MRAM is positioned to play a big role in the future of computing and storage thanks to continuous research and development initiatives.
