Storage Class Memory (SCM)

The Storage Class Memory (SCM) is a new type of memory. The SCM is a storage layer in computing systems. It functions as an intermediate layer between a memory (a volatile working memory) and a storage (a non-volatile hard disk memory). The storage layer serves to increase the efficiency and speed of the systems. At the same time, the SCM is intended to reduce the costs of storage. An important feature of the SCM is that the data is stored after the system is switched off. In contrast to conventional hard disks or SSDs, faster access times and higher data transfer rates are possible with the SCM. However, SCMs are more suitable as an additional storage for SSDs to increase the performance of applications. Therefore, SCM drives are not a replacement for SSDs.
