The terms and conditions of the deal were not disclosed, but reports suggest that the Korean giant was keen to obtain the firm's "ultra low power" Wi-Fi technology.
Samsung is expected to incorporate the tech into future tablets and smartphones to minimise the battery-draining effects of Wi-Fi.
The company today announced that its Galaxy S handsets have now shipped more than 50 million units worldwide, with the original Galaxy S accounting for 24 million, and the Galaxy S2 managing 28 million.
Samsung released its flagship Galaxy S3 device earlier this week in Europe in other territories. The device has been tipped to become its best-selling to date once it completes its global roll out.
The Galaxy S3 is expected to face stiff competition from Apple's iPhone 5, which has been rumoured for release in September or October.
