Since July 2015, China's Tsinghua Unigroup has offered to acquire or invest in the world's second largest memory maker Micron, leading US hardware vendor WD (Western Digital), and leading IC packaging and testing vendor PTI. Although Micron has turned down the takeover bid, Tsinghua Unigroup has made successful investment in WD and PTI, becoming the two companies' largest shareholder.

An observation of Tsinghua Unigroup's investment targets in 2015 shows Tsinghua Unigroup has sought partnerships with vendors in the memory industry. This report will analyze the development of Chinese memory industry from Tsinghua Unigroup's recent M&A deals, followed by their potential influences.
