IDT’s SRAM Value Proposition IDT is a pioneer in SRAM technology with proven record 1st in the industry to use CMOS for mass manufacturing Introduced many ground-breaking memory products of its time, e.g. 1st 1M device, 1st CMOS FIFO, 1st Dual-port, 1st Four-port… Inventor of ZBT SRAM architecture Co-inventor of QDR SRAM architecture and member of QDR SRAM consortium Unmatched product longevity – 6116 is over two-decades old! We provide continuity of supply in an uncertain market Continued investment in insuring quality, usability, competitive cost, etc - e.g. Green package initiative ZBT SRAM improved upon PBSRAM by eliminating idle cycles between read and write operations on the data bus. QDR SRAM is “the solution” for next generation networking architectures. QDR SRAM provides unmatched bandwidth and performance, with a wide variety of product options for customer to choose from depending on the nature of their application. © IDT CONFIDENTIAL

Telecom Value Propositions Industry First ! Telecom Value Propositions Leading standard physical interface products in the industry Industry’s First Octal and Dual J1/E1/T1 Transceivers – SuperJETTM Industry’s First Complete Family of Universal LIUs – enabling single BOM for multi-market, multi-apps Industry’s First high-density rate-matching 32k x 32k TSI Switch Industry’s most-optimized T1/E1 interface solution, HD-LIU, for SONET/SDH applications Credible and fast growing Telecom IC supplier About 30 million analog lines deployed around the world, carrying live data & voice everyday More than 10 million T1/E1 lines shipped, mainly for optical transport aggregation Hundreds of confirmed wins including key OEMs literally from “A” to “Z”, and everyone in between Top system vendors in the Metro Optical Transport market have selected IDT’s DS1 physical interface solutions for their next-gen platforms First-class applications support Effective and responsive design help tailored to engineers’ needs Design Acceleration Kits to shorten time-to-market and reduce risks: reference designs, demo/eval boards, behavior models, software drivers SuperJET = J1/E1/T1 transceiver, combining framer and LIU in a single chip IDT is the first to offer an Octal (Exar announced recently), and a Dual (still the only one). The SuperJET family leverages superb mixed-signal design expertise and the universal LIU (ULIU) technology. E.g. software impedance matching capability to allow single hardware design (BOM) for either T1, E1 or J1 in long-haul or short-haul applications. IDT’s DS1 physical layer solution has been recognized as the undisputed technology leader by leading vendors in optical transport, multiservice switch and wireless infrastructure. LIU – Line Interface Unit SLIC – Subscriber Line Interface Circuit CID – Caller ID 2 million and grown units are working in the field worldwide – excluding Caller ID devices. CID, a mixed-signal IC for consumer communications, has been shipped over 13 million units. © IDT CONFIDENTIAL
