Magnetic memory refers to a type of data storage that uses magnetic properties to record and retrieve information. This technology is commonly found in devices like hard disk drives (HDDs) and magnetic tape. It works by changing the magnetic orientation of tiny particles on a surface to represent binary data, which computers can read and write. Another form of magnetic memory is magnetoresistive random-access memory (MRAM), which combines the speed of dynamic random-access memory (DRAM) with the non-volatility of flash memory. MRAM retains data even when power is lost, making it a promising option for future computing applications.
