摘要：The main memory currently being used is facing challenges due to its scalability, cost and power issues. Over the last few years, the number of mul ti -core processors in the market being demanded are increasing due t o their ability to handle multiple processes concurrently, thus making them the mainstream of modern computing. Multi-core systems have multiple cores integrated in a single chip and a circuit installed on such system may consist of several of such chips. With systems shrinking, the size of the electrons p er cell is also reducing which is creating problems in voltage induction and charge sto rage. Thus, the main memo ry is alrea dy reaching to its cost as well as power limits. Also, scaling D RAM o n and above 40 nm is getting increasingly harder, making it inept for future systems and Cloud Computing services. PCM combines the b est characteristics of various memory types, which makes it compelling for system architects for future high end applications and products to take its benefits. This paper enlightens the scope of the multilevel Phase Change Memory (PCM or Pram) in future memory systems as it has much to offer in terms of scalability, speed, storage density, non-volatility and less energy consumption that makes it fit for technologies like cloud and computing systems of the future.
