CONTENTS INTRODUCTION HISTORY CARBON NANOTUBE STORAGE IN NRAM ADVANTAGES LIMITATIONS USES OF NRAM CONCLUSION REFERENCES

Introduction Product of Nanotechnology Non volatile memory Faster & denser Large Data storage

History Nanotechnology since 1960s NRAM by Nantero (Dr.Thomas Rueckes) Carbon nanotube

CARBON NANOTUBES Developed by Sumio Iijima An implementation nanotechnology Active memory element

CARBON NANOTUBES

CARBON NANOTUBES Advantages Disadvantage Very small in size. Low power consumption Disadvantage High cost Requirement of high precision Occurrence of impurities

STORAGE IN NRAM By positioning of charges. Data retained until overwritten or resetted. An electric field moves over array of nanotubes. Read and write by an electric field

STORAGE IN NRAM

ADVANTAGES Faster & denser Low power consumption Data storage Boot up

LIMITATIONS Over supply of DRAM Is relatively costly NRAM is still in research phase

USES OF NRAM Flash memories into camera and cell phone High speed network server Instant booting Faster and denser

CONCLUSION We could say that the prospects of nanotechnology are very bright. Nanotechnology will be an undeniable force in near future Beginning &usage of NRAM will give rise to instant ON computers
