The Difference Between DRAM And SRAM

Random Access Memory, more commonly known as RAM, is a form of computer memory that is essential for standard operations. RAM is a form of short-term memory device that works closely with the processor of a computer, serving to temporarily store and work with data that the processor needs to run programs and applications, open files, and more with extreme speed as compared to hard drives and other permanent data storage solutions. RAM comes in one of two main types, those being SRAM and DRAM. While SRAM stands for Static RAM, DRAM stands for Dynamic RAM. Knowing this, what are the major differences between the two, and when are each used?

SRAM (Static Random Access Memory) is often known for using less power than DRAM while presenting increased performance, this being a result of its lack of refreshing during operations and the presence of on-chip memory. SRAM may be found in a number of assemblies and applications, common examples including within hard drive cache, microprocessors, modern appliances, routers, peripheral equipment, and more. While SRAM boasts increased speeds and longer data life, it is not without any downsides. With these advantages comes a higher price tag, making it most suitable for applications that need those specific benefits. For installation, SRAM will generally be placed between a processor and the main memory.

With dynamic memory, large amounts of data can be stored at one time for use, relying on off-chip memory for operations. This results in longer access times and increased power usage, and it is important to remember DRAM has to be refreshed. Nevertheless, DRAM is the cheaper solution, and its installation on the motherboard makes it a widely used choice for processor memory. For common uses, DRAM (Dynamic Random Access Memory)may be relied on in system memory, CPU bus connections, smartphones, laptops, digital electronics, and graphics cards. In many of these applications, the main reason for DRAM being used is for the benefits of high-capacity memory.

With varying benefits between the top options, one may wonder which is best, or if they can be used together. To answer the second question first, SRAM and DRAM actually can be used alongside one another, and they can sometimes complement the strengths and weaknesses of each other. For example, the latency between the two RAM types can actually be beneficial, and using both can allow you to get the best of what both have to offer, as downsides are balanced to a degree.

When it comes to actually choosing between one or the other, it will come down to how you wish to best balance your needs and budgets. If space and price are not a concern while performance is paramount, SRAM will most likely be the best choice for your needs. If you simply wish to build or upgrade a computer with enough performance to efficiently carry out most standard tasks like internet browsing, working electronically, or even running semi-intensive programs, DRAM will still be a great option while saving you money.
