What fundamental properties of matter are exploited to implement memory systems? Can you think of any properties that have not yet been exploited and suggest ways in which they may be used to construct memory systems in the future?
What will be an ideal response?
If it can have multiple stable states, it can be used to store data. DRAMs store data as a charge on a conductor. Magnetic devices store data are the orientation of domains in ferromagnetic materials. Ovonic memories store data as the structure of a solid (amorphous or crystalline). Optical memories store data as
physical bumps on a substrate or as the phase of a particular material that rotates the plane of polarization.
In the future they may develop materials whose color can be changed electronically and the change detected. Holographic technologies have long been suggested as a means of data storage using laser generated holograms. Chemical memories based on changes in protein molecules have also been considered.
