SRAM memory is a kind of random access memory, the so-called "static", refers to this kind of memory, as long as keep electricity stored data can maintain a lasting, compare the DRAM memory stored inside the data needs to be updated periodically to make, but when the power supply stops, SRAM memory stored data will disappear, so an SRAM memory, also known as volatile memory, it's like after a power outage can also store data in the ROM or FLASH memory is different, SRAM memory with high performance, are widely used in applications in high-end products,
SRAM is used for:
Gm's product line 1.
Asynchronous interfaces, such as 28 needle 32 kx8 chip (usually named XXC256), and similar products up to 16 Mbit per piece
Synchronous interface, usually used for caching (cache), and other requirements of sudden transmission applications, up to 18 Mbit (256 kx72) per piece
2. The integration within the chip
As the micro-controller RAM or cache (usually from 32 bytes to 128 kilobytes)
As main caches of powerful microprocessors, such as x86 series and many other CPU (from 8 kib to magnitude of millions of bytes)
3. As a register
For specific ICs or ASIC (usually in thousands of byte order of magnitude)
Used for FPGA and CPLD
4. The embedded application
Industrial and scientific use of many subsystems, such as automotive electronics is to use an SRAM, a lot of modern equipment is embedded with the thousands of byte SRAM, in fact almost all modern equipment has realized the electronic user interface is likely to be using an SRAM, such as electric toys, digital cameras, cell phones, stereo synthesizer tend to use a few megabytes of SRAM, such as real-time signal processing circuits are often used duplex (dual - ported) SRAM,
5. Used for computer
SRAM is used for PC, workstations, routers, and peripherals: internal CPU cache, using external a burst of SRAM cache, hard disk buffer, the router buffer, and so on, the LCD display or a printer is usually SRAM is used to cache data, an SRAM do small buffer is also often used in CDROM and CDRW drives, usually for 256 KiB or more, is used to track data buffer, cable modems and similar connection to computer equipment is also used by the SRAM,
