SK Hynix said it would invest 20 trillion won or $17.8 billion in a new memory chip manufacturing plant opening on Thursday in South Korea, about 29 percent more than originally budgeted.
A company official said the chipmaker had already spent about 2.2 trillion won on the plant.
“Timing for equipment installation shall be decided considering market conditions,” SK Hynix said in a statement.
Prices for NAND chips, used for longer-term data storage, more than halved over the past year as supply swamped demand, data from market trackers show.
Those drops are expected to accelerate, while most analysts also predict DRAM prices will begin to decline, analysts say.
