1964: Static Random Access memory (SRAM)
The first traces to SRAM date back to 1964, when 64-bit Metal Oxide Semiconductor (MOS) Static RAM was developed at Fairchild Semiconductor. However, the breakthrough came when Intel developed its first 256-bit static RAM (SRAM), the 1101 chip in 1969 and formally launched it in 1971. The 1101 was the world's first MOS memory in mass-production and was first to use MOS silicon gate technology.
Other than DRAM, SRAMs do not need to be periodically refreshed and support data remanence, but exhibit volatile characteristics and lose their content when not connected to an active power source. Typically, applications today include MOSFET for CMOS. SRAMs are also used as stepping-stone technology to develop new semiconductor production processes.
