The American company Apple, due to pressure from the authorities, abandoned the components of the Chinese company Yangtze Memory Technologies (YMTC) for the iPhone. It is reported by the Nikkei.
According to the publication, Apple managed to complete the certification of 128-layer NAND memory modules from YMTC in order to start their mass production at the facilities of a Chinese partner, but at the last moment, for some unknown reason, abandoned this idea.
It seemed that YMTC products were not ordered by Apple due to pressure from the US government that put YMTC on an unverified list of companies that US businesses cannot do business with. For this reason, Apple engineers had to change the design of the iPhone at the last moment.
