What is MRAM?

MRAM, also know as magnetoresistive RAM or magnetic RAM, is a type of non volatile RAM memory which uses magnetic charges in order to store data. This is different from SRAM and DRAM, which use electric charges to store data. The advantage of MRAM is that it retains data when power is turned off. It requires only a small amount of electricity to be able to store data bits. MRAMs work by using two iron plates which "sandwich" a thin insulating layer. One of the iron plates is a magnet which is set to a specific charge, whereas the other plate is variable and allows for the polarity to change according to the pull of the external fields. Millions of magnetic "sandwiches" work together to make up the MRAM memory device. MRAM requires less power than other memory storage systems because it writes and stores data by using magnetic fields instead of electrical circuits.

Types of MRAMs

There are several different kinds of MRAMs. At Future Electronics we stock many of the most common types categorized by temperature range, memory density, memory organization, maximum access time, interface type, packaging type and nominal supply voltage. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for memory density are 256 kb, 1 Mb and 4 Mb. We also carry MRAMs with memory density up to 16 Mb. Temperature can have a range up to 125 oC or as low as -45 oC, with the most common range being between -40 oC and 85 oC.

MRAMs from Future Electronics

Future Electronics has a complete selection of MRAMs that can be used for devices that require a magnetoresistive / magnetic random access memory chip or an SPI MRAM. Simply choose from the MRAM technical attributes below and your search results will quickly be narrowed in order to match your specific MRAM application needs. We deal with Everspin Technologies as an MRAM manufacturer.

Applications for MRAMs:

Magnetoresistive RAM, or magnetic RAM, is a relatively new technology. It however has so many advantages that it may eventually become the leader in memory and thus become a truly universal memory. MRAM has been proposed for devices in as many fields as: PCs, digital cameras, notebooks, smart cards, aerospace and military system, cellular telephones, battery-backed SRAM replacement, cellular base stations, black box solutions, book readers and media players, among other uses.

Choosing the Right MRAM:

When you are looking for the right MRAMs, you can filter the results by various attributes with the FutureElectronics.com parametric search: by Memory Density (256 kb, 1 Mb, 4 Mb, 16 Mb), Nominal Supply Voltage (up to 3.6 V) and Maximum Access Time (from 35 us to 35 ns) to name a few. You will be able to find the right magnetic / magnetoresistive random access memory chip or an SPI MRAM or any of your circuits.

MRAMs in Production Ready Packaging or R&D Quantities

If the quantity of FRAMs that you require is less than a full reel, we offer customers many of our FRAM products in tube, tray or individual quantities that will help you avoid unneeded surplus.

In addition, Future Electronics offers its clients a unique bonded inventory program designed to eliminate potential problems that could arise from an unpredictable supply of products containing raw metals and products with long or erratic lead time. Talk with your nearest Future Electronics branch and find out more on how you and your company can avoid possible shortages.
