ChangXin Memory Technologies (CXMT) this month announced that it signed a patent license agreement with Rambus to get access to a wide variety of DRAM patents.

Under the aggrement, CXMT says it has been granted a license to a wide range of Dynamic Random Access Memory (DRAM) patents from Rambus.

“The agreement with Rambus once again demonstrates our high attention to international intellectual property (IP) related rules and continued efforts to strengthen the company’s IP portfolio,” said Yiming Zhu, Chairman and CEO of CXMT.

“In order to achieve sustainable growth and gain competitiveness in the market, we are committed to continuously building upon our technology and IP assets through independent R&D efforts combined with global cooperation,” Zhu added.

“The Chinese DRAM market has seen considerable investment with CXMT emerging as the leader of China’s DRAM industry,” said Luc Seraphin, president and CEO of Rambus. “We are pleased that they have joined the global DRAM industry and have signed this long-term agreement, securing the rights meaningful to their business and recognizing the fundamental value of the broad Rambus memory patent portfolio.”

Other information related to the agreement was not disclosed.

Within four years, ChangXin Memory Technologies has risen to become China's largest DRAM manufacturer. The chipmaker is a crucial piece in the domestic semiconductor industry as China continues its push for tech self-sufficiency. ChangXin Memory Technologies currently produces DDR4 and LPDDR4X products.
