NEC has said its restructuring could include job cuts at a semiconductor plant in Scotland and postponing a boost in chip output at a Chinese joint venture.
The company is Japan's second-largest chipmaker and employs about 400 people at a semiconductor plant at Ballivor in Co Meath.
"Two months ago we cut staff in the US and now they're examining how to restructure the UK, as well as China and other areas," NEC spokesman Mr Daniel Mathieson said, although he said no decisions had been made.
He said he could not confirm a report in the Nikkan Kogyobusiness daily that NEC had decided to cut jobs and output capacity at the Scottish plant, which employs 1,570. The report also said NEC had frozen a plan to boost semiconductor production capacity by 25 per cent at a joint venture in Shanghai.
NEC has been aggressively restructuring and in April announced plans to cut 700 jobs at a California chip plant due to declining semiconductor demand.
It also said it would halt the facility's production of DRAM (dynamic random-access memory) chips and shift to higher-margin devices.
Details of NEC's next round of restructuring are expected late this month with the annual announcement of mid-term management targets.
