SRAM (static random access memory) is a type of memory that is used in many electronic devices, such as computers and microcontrollers. Unlike other types of memory, such as DRAM (dynamic random access memory), SRAM does not need to be refreshed in order to retain its data. This makes SRAM faster and more power-efficient than DRAM, but also more expensive and less dense.
SRAM is typically used in applications that require fast access to data, such as in the processor caches of computers. It is also commonly used in devices that require low-power operation, such as in portable electronic devices and in some automotive and industrial applications. SRAM is typically more expensive than other types of memory, but it offers superior performance in terms of speed and power consumption.
