Consumer electronics comprises of electronic equipments intended for everyday use, most often in entertainment, communications and office productivity. By definition, a product containing an integrated circuit or IC - a small electronic device made out of a semiconductor material, is called an electronic product. At the heart of an integrated circuit, there is microprocessor which is a semiconductor chip which can be programmed to do various functions. According to Moore\'s Law, for a given price, the semiconductor functionality doubles every two years. Due to the ever-growing demands for light weight, faster and compact consumer devices, the silicon chip is undergoing tremendous pressure for further miniaturization. These demands at the integrated chip level, pose uphill tasks before a material scientist like say, develop a chip interconnect more efficient than copper, develop an inter-dielectric with as low K as possible, and develop a gate dielectric better than silica. On top of this, we will reach a point where the very existence of silicon itself is at stake due to the internal heat and leakage current at atomic level. The storage capacity of the memory devices are also tremendously expanding. Hence more energy efficient devices based on spintronics and magnetoelectric phenomena are actively pursued. Developing such a multiferroic memory is expected to reduce the memory cell size to less than 20 nm while maintaining a capacity of 1Tb/(inch)2
