What is RAM and what does RAM do? Updated 28-January-2025 in About Memory RAM, also known as computer memory, is one of the most vital components in your desktop, laptop and MAC. For anyone wondering what RAM does, how it works in your computer and why you might need to upgrade it...
What does DRAM do? All RAM types, including DRAM, are a volatile memory that stores bits of data in transistors. This memory is located closer to your processor, too, so your computer can easily and quickly access it for all the processes you do. As you use your computer, it needs to...
DRAM is a successor to SRAM. Memory designers reduced the number of elements per bit and eliminated differential bit lines to save chip area in order to create DRAM. As a result, DRAM is less expensive to produce than SRAM. But SRAM retains some advantages over DRAM. SRAM does not need t...
That said, in this article, we’ll be focusing on RAM—what is it? What does it do? What types of RAM are there? How much of it do you need in a gaming PC? We’ll be answering all of those questions below, so if you’re interested in finding out more, read on with this gui...
Static random access memory (SRAM).This type of RAM is typically used for the system's high speed cache, such as L1 or L2. Like DRAM, SRAM also needs constant power to hold on to data, but it doesn't need to be continually refreshed the way DRAM does. SRAM is more expensive than...
SSD vs. HDD: Which Do You Need? What Is the Difference Between Thunderbolt and USB-C? 11 Reasons Why Your Phone Is Overheating AMD vs. Nvidia: Which Is the Best GPU? AMD vs Intel: Which CPU Is Better in 2023? What Is a Solid-State Drive (SSD)? What Is RAM and Why Does Random...
What does this mean for PCs? Getting back to PCs, our long-term storage devices are incredibly slow, at least when compared with a CPU's speed. SSDs can read and write data at 500MB/s to 4GB/s, which is several orders of magnitude slower than a fast CPU (1,800GB/s). A hard ...
So where does DRAM fit within the larger world of storage? In this section, we’ll take a closer look at some common speed comparisons to get a general idea of how DRAM stacks up to other types of storage media. DRAM vs. HDDs and SSDs As a non-volatile storage media, DRAM is inh...
SSDs store data on a number of memory cells known as NAND flash. During the SSD’s lifespan, data is moved around these cells quite a bit. It does this automatically to ensure that no single memory cell is worn out due to repeated reading/writing. As a result, your SSD needs to kee...
Servers with SSD storage SSDs have been gaining ground for years now. Until recently, these flash-based storage devices have been mostly used by mobile devices, like smartphones or MP3 players. But more recently desktops and servers have been making use of this technology. What advantages do ...
