Abstract:
Electronics and nanotechnology working together would yield a holistic solution to data storage problems that are encountered with conventional techniques. This paper aims at familiarizing the reader about some of the available and emerging data storage technologies which are direct consequences of advancement of nanotechnology. The applications along with their concepts covered in the paper are
1. EEPROM
2. Flash Memory
3. FerroElecric RAM- dubbed as FeRAM
4. MRAM
5. Conductive Bridging RAM- CBRAM
6. PRAM
7. SONOS
8. RaceTrack memory
9. NRAM
10. Twin-Transistor RAM-TTRAM
11. ZRAM
12. Memristor
Besides explaining the technique of data storage in each of the above mentioned applications, this paper also gives an appreciable comparison between existing technologies and emerging technologies.
Introduction:
A data storage device is a device for recording information. Electronic data storage is storage which requires electrical power to store and retrieve data. Most electronic data storage devices are volatile in nature for the data stored vanishes if it is devoid of power although efforts are under way to create permanent (non-volatile) data storage using electronic applications.
Trends in data storage:
International Data Corporation estimated that the total amount of digital data was 281 billion gigabytes in 2007, and had for the first time exceeded the amount of storage.
Before moving any further in understanding emerging trends in electronic storage, we here briefly describe an EEPROM and then comprehensively cover a few
