Elpida Memory Inc., the last domestic maker of DRAM chips, was delisted from the Tokyo Stock Exchange Wednesday in the biggest corporate failure in Japanese manufacturing history.

Elpida's failure has shed light on the severe environment facing domestic semiconductor manufacturers, which could accelerate moves to form tieups with other firms — including foreign ones — to keep up with rivals.

Elpida, the sole dynamic random access memory maker in Japan, was given court approval last week to start a rehabilitation procedures after filing for bankruptcy in February even though it received government investment in 2009 to enhance its financial base.
