What is Sram?
Statical memory with random access (SRAM) is a type of RAM used in various electronic applications including toys, cars, digital devices and computers. It only holds its content while the power supply is used. This type of memory differs from the dynamic RAM (DRAM) in this DRAM must use recovery cycles to keep its content alive. SRAM keeps data as a static "picture" as shown in the name until it is written or lost from turning on. However, its internal structure is also less dense, and therefore less ideal candidate for the main memory within personal computers. Instead, SRAM is used for critical secondary use, such as fast cache for central processing units (CPU). The CPU cache can significantly increase the overall performance of the computer with a relatively small trace of reserved memory.
Compared to DRAM, SRAM is more efficient when it is idle. overclocking Overclocking causes CPU to work faster than its specificationon the market. In this case, SRAM spends less time in the inactivity mode.
SRAM is also present in many modern hard drives as a disk cache. The disk cache is used to temporarily storage of data that are often accessible. Getting data from the cache is many times faster than obtaining it from a standard hard disk designed by a plate. People can also find SRAM in modern routers, printers, digital cameras and compact disk (CD) or digital universal disk (DVD). Toys with electronic interfaces also commonly use this type of memory.
Static RAM can be synchronous or asynchronous . Asynchronous Sram is not dependent on CPU hourly frequency, while synchronous synchronizes with CPU speed.
SRAM can be incorporated one of the two types of transistor chips: bipolar fastenersTransistor or metal-oxide-delemiconductor-effect-effect-effect transistor (mofset) . The first makes SRAM extremely fast, but also consumes a lot of energy. This type of transistor is used in special applications. Mofset is a more common type of memory used in various applications discussed here.
Computer users should not confuse Sram SDram or synchronous dynamic memory with random access. SDRAM is a DRAM flavor and works differently.
