SRAM ICs

SRAM (Static random-access memory) is a type of random access semiconductor memory which is a volatile memory (meaning that its data is lost when power is turned off), and stores each bit of data generally in flip-flops. The frequent refreshing activity is not required, unlike in DRAM. As long as power is there the data will be retained without refresh. One SRAM memory cell contains 6 transistors (four transistors configured as two cross-coupled inverters and two additional transistors to control the access to the memory cell). A basic SRAM provides fast data access but holds less data per unit volume, so they are more expensive than DRAM. They are commonly used in cache memory, video card memory, etc.
