В начале 2008 года Spansion купил Saifun Semiconductors по цене около $ 368 млн.
Saifun Semiconductors has more fun with non-volatile chips. The company offers intellectual property (IP) designs for non-volatile memory (NVM) semiconductors. Saifun licenses its IP to chip makers for incorporation into their own flash memory chips and other devices. Saifun touts its NROM (nitride read-only memory) technology as allowing chips to retain more data at lower costs in comparison with competing products. Among the company's licensees are Macronix International, NEC Electronics, and Sony. In early 2008 Spansion bought Saifun for about $368 million in cash and stock.
