Static random access memory (SRAM) is a type of computer memory used for running processes, but not for long-term storage. It is faster than dynamic random access memory (DRAM) but requires more space and is more expensive. SRAM is usually volatile and requires power to retain data, while non-volatile memory is used for storage.
Static random access memory (SRAM) is a form of computer memory typically used to read and write when programs and processes are running. It’s usually volatile, meaning it requires energy for data to stay in it, so it’s not used for long-term storage of information. Static random access memory is designed to hold data on it, while powered, without being updated continuously, allowing it to run faster than other types. Unlike Dynamic Random Access Memory (DRAM), however, the SRAM design allows for only a fairly small amount of memory on a small board or chip and is more expensive.
While the term “memory” can be used to refer to computer data storage, it most often means processing power through something like static random access memory. Most SRAM is volatile and therefore only holds the information it is reading or writing as long as it is powered. Nonvolatile memory is typically used for storage, such as a hard drive, because it can retain data even without power. There are non-volatile forms of static random access memory, but they are quite rare, typically only used within small electronic devices and appliances.
Static random access memory is basically used for running processes, both by reading and writing data. As a computer is used to run a program or read information from a storage device, the processor inside the computer determines how quickly the data can be accessed. This information is read or written from something like static random access memory, which may hold data while the computer is being used, but doesn’t contain it afterward. The term “static” means that SRAM can keep the information on it, as long as there is power, without the computer periodically updating it.
Unlike static random access memory, there is also dynamic random access memory or DRAM, which is commonly used as the main processing memory inside personal computers. DRAM is typically volatile memory, but is designed to hold data only through frequent updates by the computer system. Since SRAM does not require this upgrade from the processor or computer, it can read and write information faster than DRAM. Static random access memory architecture, however, requires more space than DRAM, making it inefficient for memory-intensive applications. SRAM is also more expensive than dynamic memory, so it’s typically used in more specialized applications such as memory for processors and devices like printers.
