BEIJING—Samsung and other NAND Flash memory chip manufacturers have begun quoting memory chip prices again, after Chinese authorities ended a pandemic lockdown of the city Xi’an earlier this month. When the lockdown was first announced, suppliers stopped quoting prices because closed-down transportation systems prevented workers from reaching company fabs.

Samsung issued a statement at the time, saying “we have decided to temporarily adjust operations at our manufacturing facilities in Xi’an. We will also take all necessary measures, including leveraging our global manufacturing network, to ensure that our customers are not affected.”

Samsung employs 3,300 people in Xi’an where it has two fabs that produce 40 percent of Samsung’s total NAND output. Most of this output supplies the China market.

Micron operates its DRAM plant in Xi’an. This plant is back to normal operations after temporarily rescheduling shifts with reduced staffing levels during the lockdown.

NAND memory chips are found mainly in memory cards, USB flash drives, solid-state drives (those produced since 2009), feature phones, smartphones and similar products for general storage and transfer of data.
