Elpida Memory Inc, Japan’s largest computer-memory chipmaker, rose the most in more than a week in Tokyo trading after rival Qimonda AG filed for insolvency, easing competition amid a glut.
Elpida climbed 6.4 percent to close at ¥546 (US$6.15) on the Tokyo Stock Exchange.
The insolvency may help reduce supply growth in the US$25 billion memory-chip industry this year, especially for graphics and server semiconductors, California-based ISuppli Corp said in a report after Qimonda’s announcement on Friday.
Munich-based Qimonda’s factories account for 5 percent of global output of dynamic random access memory, the researcher said.
Qimonda, a unit of Infineon Technologies AG, said it sought protection from creditors after failing to secure financing as an oversupply led memory-chip prices to fall 51 percent last year.
“This could help right the demand-supply balance in the long term, but we don’t foresee any immediate impact,” Kumiko Higuchi, a spokeswoman for Elpida in Tokyo, said by telephone yesterday.
