US memory-maker Micron has no idea why Chinese authorities have decided its products represent a security risk, or which customers it's not allowed to sell to.

Micron CFO Mark Murphy on Monday told J.P. Morgan's 51st Annual Global Technology, Media and Communications Conference that China's Cyberspace Administration, which on Sunday announced the chipmaker had failed a security review, has offered no reason for that opinion.

The consequence of failing that review was a ban on Chinese "Operators of critical information infrastructure" buying Micron products.

The low-end impact estimate assumes China will ban "Principally networking companies" from acquiring Micron products, while the high-end estimate would see what Murphy described as "Different markets" come into play.

Murphy said Micron intends to offer more detailed guidance on what China's ban will mean for the chip shop's finances during its next quarterly results announcement in June.

China's decision to ban Micron complicates geopolitical matters considerably The ban has been interpreted as Beijing flexing its muscles with an act that harms a US business, and which comes at little cost to China as the products Micron makes are widely available - from both Chinese suppliers and from Korean giants Samsung and SK hynix which make such kit in China.
