Memory architecture balances different types of computer memory, including RAM, cache, flash, and file storage, to optimize performance and reliability. Memory types vary in cost, speed, and permanence, with processor registers and cache being the fastest and most expensive, and file storage being the slowest but most stable for retaining information after a power cycle. Virtual memory on the hard drive is a cost-effective option for persistent mass storage.
Although the most common type of computer memory is random access memory (RAM), there are many other types of memory that can be used in a computer. These include cache memory, flash memory and file storage. Memory architecture refers to the combination of different types of memory to balance a computer’s performance without compromising storage reliability or making the computer cost-prohibitive. In general, the different types of memory run on a hierarchy ranging from fast and expensive to slower and less economical. Memory architecture works to ensure that your computer has a mix of all types of memory, keeping your computer hardware as balanced and efficient as possible.
In addition to differing in cost and speed, memory also differs in permanence. Standard RAM in a computer is a dynamic form of memory, which means it only holds information as long as the computer is turned on. This presents an obvious problem when it comes to retaining information on your computer after a power cycle, because without a more persistent form of memory, all information on your computer would be lost in the event of a power outage. File storage memory inside the computer (the most common example is a hard drive) provides a relatively slow but stable method of retaining information on the computer after it is shut down.
Processor registers and cache memory are usually the fastest and most expensive. By locating these types of memory on the physical processor chip, transfer time and latency for these types of memory are greatly reduced. This means that information can travel to and from these types of memory in the blink of an eye, making them efficient for holding information and variables while the processor is actively working on a specific problem.
RAM is next level, both cheaper and slower than processor registers and cache memory. This is connected to the processor via the front bus, which means that latency increases while speed decreases relative to register and cache memory. The cost also drops substantially, making RAM the most cost-effective form of dynamic storage in the memory architecture.
Finally, virtual memory and file storage locations are usually kept on the hard drive. Virtual memory is a section of the hard drive that your computer’s operating system treats as RAM. Hundreds and hundreds of gigabytes of hard drive storage can be purchased for the same amount as just four to eight gigabytes of RAM, making it the best persistent mass storage location on a computer’s memory architecture.
