Memory technology licensor and chip vendor Rambus Inc. is working with a financial advisor to study options for its sale, according to a report by Bloomberg.

No final decisions have been made about selling the company, according to the report, which cites anonymous sources.

Rambus declined to comment on the report.

Rambus is a Sunnyvale, Calif.-based company with a long history of patent litigation, including successful litigations against many of the largest memory chip vendors. After years of collecting significant royalties from its double data rate (DDR) technology and earning a reputation as a patent troll, Rambus returned to its roots as a fabless chip vendor in 2015.
