SK hynix's (KRX:000660) U.S.-based NAND flash subsidiary Solidigm's potential listing in the U.S. is still undecided, the chipmaker said in a Thursday release.

The South Korean firm said it was reviewing several options to boost Solidigm's competitiveness, including investment and capital allocation, while considering its overall investment plans, financial position, and shareholder value, it said.

Solidigm was launched during SK Hynix's acquisition of Intel's NAND and solid-state drive (SSD) businesses.
