(exechange) — Sunnyvale, California, June 28, 2018 — Ron Black, chief executive of Rambus, leaves. It is an abrupt change. As announced by Rambus Inc. in a news release and in a regulatory filing published on Thursday, June 28, 2018, Ronald (Ron) Black leaves his post as Chief Executive Officer at the technology licensing company after about six years in the role, effective immediately.

Among the 3,000 largest publicly held companies incorporated in the U.S. based on market capitalization, the average tenure of the CEOs who departed over the past 12 months was 9.5 years, according to data compiled by exechange.

Rambus will undertake a search for a successor.

Black’s duties will be taken over in the interim by Luc Seraphin, most recently Senior Vice President & General Manager, Memory and Interfaces Division of Rambus Inc.

“Dr. Black’s conduct fell short of the Company’s standards”

Black’s sudden departure from the CEO post is explained as follows. Rambus said in a fairly blunt statement: “The termination follows an incident unrelated to the Company’s financial and business performance in which the Board determined Dr. Black’s conduct fell short of the Company’s standards.”

Precise information about Black’s future plans was not immediately available.


Rambus said: “the Company’s Board of Directors has terminated Dr. Ron Black as Chief Executive Officer, effective immediately.”

Rambus further said: “On June 27, 2018, the Board of Directors … of Rambus Inc. … terminated Dr. Ronald Black as President and Chief Executive Officer, effective June 28, 2018.”
