The EU Commission has fined the world's biggest memory chip makers, including Samsung, Infineon and Toshiba, a total of €331m for operating a cartel.
The biggest fine - €145m - was handed down to South Korea's Samsung Electronics. Germany's Infineon Technologies was fined €56.7m while South Korea's Hynix Semiconductor will have to pay €51.5m.
Other companies fined for being part of the cartel include Japanese firms Hitachi, Toshiba, Mitsubishi, NEC Electronics and Elpida Memory as well as Taiwan's Nanya.
US chip maker Micron Technology blew the whistle on the price fixing cartel and therefore escaped any fine.
The European Commission said the overall fines had been reduced by 10% after the companies acknowledged their involvement in the cartel. It was the first time such a settlement had been reached in a cartel case.
'The companies concerned have acknowledged that they coordinated prices,' EU Competition Commissioner Joaquin Almunia said.
