For memory improvements, several forms of nonvolatile RAM (NVRAM) are becoming available or are under development. Please briefly define & describe MRAM, PRAM, and NRAM. Also explain some current and future applications for NVRAM.

Magnetoresistive RAM (commonly referred to as MRAM) uses magnetic polarization rather than an electrical charge to store data. PRAM (phase change random access memory) has a special coating that changes its physical state when heat is applied (similar to the recordable CDs and DVDs). NRAM uses carbon nanotubes. The most common applications for nonvolatile RAM today include storing critical data for enterprise systems as they operate to guard against data loss and saving the data necessary to help industrial automation and robotics systems recover quickly from a power loss. Other emerging applications include “instant-on” computers and mobile devices that can be turned on and off like an electric light, without any loss of data. It is expected that a form of nonvolatile RAM will eventually replace SDRAM as the main memory for a computer.
