Typical applications are programmable controllers or indeed any type of machine where alterable Parameters are stored.

This kind of non-volatile memory has all the advantages of RAM - fast read/write, byte-addressable, unlimited write/erase. Data are written just as in normal RAM, but remain unchanged even without external voltage for 10 years and more.

Greenwich Instruments was the first manufacturer to supply SRAM modules with integrated Lithium cells. TecSys has been the German distributor for this line since 1984.
