Full Description

Rambus Inc. (Rambus), incorporated in March 1990, is engaged in designing, developing and licensing chip interface technologies and architectures. The chip interface technologies are designed for customers’ semiconductor and system products for computing, gaming and graphics, consumer electronics and mobile applications. Rambus also develops a range of solutions, including leadership and industry-standard chip interfaces that it provides to it’s customers under license for incorporation into their semiconductor and system products. In addition, to its leadership solutions, the Company offers industry-standard chip interface solutions, including DDRx (where the x is a number that represents a version). It also offers digital logic controllers for Peripheral Component Interconnect (PCI) Express, DDRx memory and other industry standard interfaces. The Company’s customers include AMD, Fujitsu, Qimonda, Intel, NEC, Panasonic, Elpida, IBM, Sony, Renesas and Toshiba.

The Company’s portfolio includes Fully Synchronous Dynamic Random Access Memory (DRAM), which is designed to allow precise timing from a DRAM system. The Dual Edge Clocking is designed to allow data to be sent on both the leading and trailing edge of the clock pulse. The Variable Burst Length is designed for data transfer efficiency by allowing varying amounts of data to be sent per a memory read or write request in DRAMs and Flash memory. The FlexPhase technology synchronizes data output and compensates for circuit timing errors. The Channel Equalization is designed for signal integrity and system margins by reducing inter-symbol interference in high speed parallel and serial link channels.

Rambus licenses a range of technology solutions, including its leadership architectures and industry-standard chip interfaces to customers for use in their semiconductor and system products. The Company’s leadership technology solutions include the eXtreme data rate (XDR), XDR2 and rambus dynamic random access memory (RDRAM) memory architectures and the FlexIOTM processor bus. XDR DRAM is the main memory solution for Sony Computer Entertainment’s PLAYSTATION, as well as for Texas Instrument’s latest generation of DLP front projectors. The XDR2 Memory Architecture incorporates innovations, including DRAM micro-threading, for deliver the graphics intensive applications, such as gaming and digital video. RDRAM Memory has shipped in the Sony PlayStation, Intel-based personal computers (PCs), Texas Instruments digital light processing (DLP) televisions and in Juniper routers. The Flex 10 Processor Bus is a high speed chip-to-chip interface.

The Company competes with ARM Holdings plc and Synopsys Inc.
