What is MRAM?
Magnetoresistive Random Access Memory (MRAM) is a non-volatile memory technology with properties that differentiate it from conventional silicon memory. The computer industry, would welcome MRAM as a replacement technology for EEPROM and FLASH and current DRAM, making all memory dense, fast and non-volatile. “What makes Micromem interesting is the fact that it is targeting its products at the RFID market, the only MRAM firm we are aware of that is adopting such a strategy. There is no doubt that RFID is in need of a viable non-volatile memory solution and if Micromem can reach its objective it would find itself with a large addressable market for its products/technology.” NanoMarkets Research Report, January 2005 “For the past five years, Micromem has been working on a version of magnetoresistive (or magnetic) random access memory (MRAM). By using a material’s magnetic properties to store and process information instead of relying on a material’s electronic properties, MRAM promises to
The perfect memory device has been sought by designers for decades. High Speed, high density, high reliability, low power, permanent data storage with and without power, unlimited number of accesses, infinite data retention and the ability to easily design these devices into applications are strongly desired. Magnetic Random Access Memory (MRAM) offers all of the above. MRAM operates on the principle of magnetism for storing 1’s & 0’s in memory. It has got the speed of SRAM, competes DRAM with density and has got the strong non-volatile property of Flash memory. Magnetic RAM uses the alignment of magnetic movements to store data.
MRAM stands for Magnetoresistive Random Access Memory. It is a technology whose time has not yet come, mainly because it hasn’t been needed yet. Many experts believe, however, that MRAM is on the horizon and will be implemented any time now. As its name suggests, MRAM uses magnetic storage elements to store its data. Specifically, two iron plates sandwich a thin insulating layer. One of those plates is a magnet that is set to a specific charge. The other plate is variable, allowing for changing polarity according to external fields’ pull. A collection of these elements make up the MRAM memory device. Like other RAM, MRAM consists of data. In this case, the data is written into the MRAM system using magnetic fields. Because MRAM writes and stores this data using magnetic fields rather than traditional electrical circuitry, it requires much less power than other comparable systems of memory storage. Dynamic RAM (DRAM), which is the industry standard because of its superior density and pr
