Static random access memory (SRAM) is a type of semiconductor memory. It uses bistable latching circuitry for storing bits. It is static in nature i.e. the data bits are stored till the power is supplied. The SRAMs are comparatively more expensive than DRAMs, thus are mostly used in the applications where high efficiency and performance is needed. Some characteristics such as bandwidth, power efficiency make SRAMs ideal for the electronic appliances such as cell phones, digital cameras and electronics user interfaces. Some of the general uses of SRAMs are workstations, computers, routers and other peripheral equipments such as CPU (central processing unit) caches, CPU register files, router buffers and hard disk buffers, among others. Printers and LCD (liquid crystal display) screens also use SRAM to save the preview of the image printed or displayed.
Emerging high performance network applications, increasing demand and applications of the embedded SRAMs, and increasing demand for faster cache memories are some of the factors responsible for the growth of SRAM market. Faster switching time, power efficiency and high endurance as compared to traditional RAM, effective replacement for the traditional memory technology and increasing application base are some of the driving factors for the SRAM market. However, its larger cell size (up to six transistors for a single bit) makes it impractical for applications requiring large memory. Further, high cost incurred in designing and low stability in harsh condition is some other challenges to the growth of SRAM market. Neural networks and flexible electronics are emerging opportunities in SRAM market. The market for cellular RAM is increasing at growing rapidly and use and application of SRAM in cellular devices is expected to boost the market in coming time. Flash memory market can be replaced by SRAMs in upcoming years and players have opportunity in this filed.
Static random access memory is segmented on the basis of type of flip-flop used, transistor type, features, functions, product types, applications and geography. Binary SRAM and ternary SRAM are the two broad segments of the SRAM market on the basis of flip-flop type. On the basis of transistor type the SRAM market is segmented into bipolar junction transistor and MOSFET (metal–oxide semiconductor field-effect transistor).on the basis of features the SRAM market is segmented into ZBT (zero bus turnaround) SRAM, syncBurst SRAM, DDR (double data rate) SRAM and quad data rate SRAM. SRAM market is segmented on the basis of products into, asynchronous SRAM, PSRAM (pseudo SRAM), nVSRAM (non volatile SRAM) and others. On the basis of end-use application SRAM market is segmented into communication industry, computer /IT sector, consumer electronics industry and automotive sector, among others. China, Taiwan, Singapore, India and Malaysia are some of the countries holding huge potential for SRAM market.
