Oracle is not done with acquisitions, and will look to makers of computer chips and industry-specific software next, says chief executive Larry Ellision.
Acquiring chipmakers will further Oracle's push into computer hardware following the acquisition of Sun Microsystems earlier this year, he told attendees at the Oracle OpenWorld user conference in San Francisco.
Ellison wants to follow the approach of Apple chief executive Steve Jobs, of owning the intellectual property that underpins computer chips, according to US reports.
Oracle's focus on servers means it is likely to buy a semiconductor company with technology for servers such as AMD, IBM's chip division and Nvidia, said analysts.
Ellison said Oracle also plans to buy more makers of industry-specific software, with the aim of standing out from rivals such as SAP.
Silicon and software IP is very important, said Ellison, reiterating Oracle's plans to invest $4bn (£2.55bn) in research and development in Oracle's 2011 fiscal year.
Oracle plans to boost performance and reduce costs to customers by designing hardware and software to work together, so that they do not have to mix-and-match products made by different companies.
