There are many types of memory used today. Starting with processor concrete, which is a quick, and concluding process for those we use in traditional hard drives, there are many intermediate steps, all directly applicable, human cost and production costs. The following graph prepared by WD you can see where this storage class memory is, which we'll talk about today.
What is SCM memory?
SCM appears Conservation Phase memory or storage class memory, as we showed earlier. It's the kind of memory whose main name is includes a source of energy to ensure that data is not lost when a system error or power fails. So, it's kind of a not-so-subtle but subtle kind of memory that it handles the details like a normal DRAM memory, the difference lies in that, data is not lost when there is a power outage.
In terms of performance, SCM memory is stored between RAM and Flash NAND for SSDs, and as a result of this integration there are many types of SCMs still created by companies dedicated to storage, because many believe that it will be the basis for a digital revolution in how data is stored on computers.
As you can see in the image memory pyramid, SCM memory is considered "memory" as such and not storage (albeit its name). In short, and for us to understand, it's a kind of memory faster than SSDs but not so much with DRAM, but unlike that later, it behaves like an SSD based on data continuity, that is, not-so-flexible.
Importance of SCM Memory
Storage class memory is a storage form created from NAND Flash. It's a middle step between high performance DRAM and standard hard drives, cheap to do. It can provide faster typing performance than hard drives, as well as DRAM learning performance.
SCM is considered to be an integral part of high-speed data transfer, next-generation computer in memory, as well as qualifications designed for computer installation and storage.
In some cases, SCM can be used to replace RAM, although it makes sense at a much faster speed. In this role, SCM can offer many benefits, including rapid reboot to data servers during scheduled maintenance, as well as during power outages and unexpected reboots.
Many applications and databases, especially those that require low latency, high bandwidth, and strong data integrity, can use the storage phase memory. In addition, it has the ability to speed up virtual machine storage and provide better performance in cloud applications distributed across multiple locations.
