* Settles all claims between two companies

* Samsung will invest $200 mln in Rambus stock

* Rambus shares up 9.5 pct in afterhours trade

SAN FRANCISCO, Jan 19 (Reuters) - Samsung Electronics Co Ltd (005930.KS) and Rambus Inc (RMBS.O) have settled their long-running legal battle, agreeing to a licensing and investment pact that could be worth $900 million over half a decade to the memory chip designer.

Rambus shares rose 9.5 percent in afterhours trade on Tuesday after the settlement was announced.

The two companies said in a statement the agreement included a quarterly payment from Samsung to Rambus of about $25 million for the next five years, as well as an investment of $200 million in Rambus stock.

Samsung will also pay an initial $200 million in cash to Rambus.

The agreement comes before the start of an antitrust trial in San Francisco. Los Altos, California-based Rambus had accused Samsung, Micron Technology Inc (MU.O) and Hynix Semiconductor Inc (000660.KS) of colluding to fix prices, hurting sales of Rambus' RDRAM memory chips for computers.
