Composites of "Ferroelectric Ceramics" and Polymers - a Potential Source of Non-Volatile Memory

The term memory in context of 'Computer' is usually taken as random access memory (RAM). Static RAM (SRAM) and Dynamic RAM (DRAM) are its two main forms and both are considered volatile, as their state is lost or reset when power is removed from the system. Non-volatile memory is the computer memory that can retain the stored information even when power is switched off. Flash memory is the best- known form of NVRAM memory today, which uses NAND and NOR logic gates but it has the drawback of high power requirement which places another drawback making it slow in operation as high power requires more time to attain its high level. The system with very low power consumption and faster in operation is given by Ferroelectric-RAM. 'Ferroelectric- Ceramic'-polymer composites which are considered as potential source of Non-Volatile memory are discussed in this paper.
