Kioxia Holdings Corp, the world’s second-largest maker of flash memory chips, warned on Thursday that tighter U.S. restrictions on Huawei Technologies could cause memory chip oversupply and drive down market prices.

Kioxia, formerly known as Toshiba Memory, also said in a regulatory filing that all or most of its chip sales to the Chinese tech giant are highly likely to be subject to the tighter restrictions that came into force this week.
