SRAM (Static Random Access Memory)
SRAM, or Static Random Access Memory, is a type of memory device that stores accessed files and commands in a semi-permanent chip that only empties itself of stored data when it is no longer being powered, i.e. when the computer is unplugged or turned off. SRAM differs from DRAM, or Dynamic Random Access Memory, which stores data even when the computer is unplugged, but must be refreshed regularly to empty old data. While SRAM is highly efficient and very convenient for quick access, it is mostly only used to store files that are repeatedly accessed or modified, while DRAM is used to store memory of the vast majority of files and folders.
Applications
SRAM is commonly used for high-speed, high-quality applications that must have data delivered immediately in order to operate. For example, programs often use SRAM to maintain daily functions. In contrast, files and folders accessed by programs, as well as non-essential drives, generally use DRAM.
Advantages
SRAM is advantageous because it provides programs with immediate access to files and folders that they have accessed recently, especially program files. SRAM is also advantageous because it can be used in conjunction with DRAM, providing users with both fast, short-term memory and reliable, long-term memory. Additionally, SRAM can be replaced or upgraded by replacing either a single SRAM chip or an entire SRAM block.

- Random Access Memory
Random-access memory is a type of data storage for computers. Commonly known as the acronym RAM or simply memory, random-access memory details the speed in which data that is stored can be accessed at random. This means that the strength of the RAM determines, at random, how fast a piece of data can be pulled [...]...
- NVRAM (Non-Volatile Random Access Memory)
NVRAM is an acronym for Non-Volatile Random Access Memory. NVRAM is a type of Random Access Memory (RAM) that retains its information when power is turned off. The NVRAM is a small 24 pin DIP (Dual Inline Package) integrated circuit chip and is thus able to obtain the power needed to keep it running from [...]...
- RAM (Random Access Memory)
RAM (Random Access Memory) usually refers to “temporary” memory, meaning that when the system is shut down, the memory is lost. This is why the memory is considered “random,” as any piece of information can be circulated through the memory regardless of its location and relation to any other information within the RAM. The first [...]...
- What does RAM Stand For?
Random Access Memory (RAM) is a type of computer memory. It derives its name from the fact that any piece of data stored on it can be accessed at any time. RAM however stores data for as long as the computer is switched on or is in use. It is the most common type of [...]...
- Registered Memory
Registered memory modules have built-in registers on their address and control lines. A register is a very small temporary holding area (usually 64 bits) for data. These registers act as buffers between the CPU and the memory. The use of registered memory increases system reliability, but also slows the system down a very slight bit [...]...
