Sales Training 3/13/ Cypress Confidential Owner : LUOS CYPRESS INTERNAL USE ONLY GSI SQ-IIIe Overview GSI SQ-IIIe is a 72 Mb SRAM featuring Operating Speeds up to 675 MHz Random Transaction Rates (RTR) up to 1350 MT/s Quad Data Rate Interface On-Chip Error Correction Code (ECC) GSI SQ-IIIe finds application in High speed network switches and routers High performance computing GSI SQ-IIIe provides fast operating speeds and high RTR GSI SQ-IIIe

Sales Training 3/13/ Cypress Confidential Owner : LUOS CYPRESS INTERNAL USE ONLY Challenges Using GSI SQ-IIIe G networking line cards require high performance RTR 200G line rates and increased network traffic demands require RTR ranging from 1200 MT/s to 4800 MT/s GSI SQ-IIIe’s maximum RTR is 1350 MT/s, which limits the algorithm flexibility Example: GSI SQ-IIIe only supports up to 4 random transactions per lookup table per packet at 200G line rates 2. Sole sourced products are susceptible to supply interruption Memory interfaces should be standardized, ensuring the ability to source from multiple vendors GSI is the sole source provider of SQ-IIIe QDR-IV Cypress QDR-IV solves these problems: Offers industry’s highest RTR of 2133 MT/s, can support up to 7 random transactions per lookup table per packet at 200G line rates Multi-source product carried by all 3 global electronics distributors, 11 local distributors and 3 catalog houses QDR IV is the highest performing, standardized networking memory

Sales Training 3/13/ Cypress Confidential Owner : LUOS CYPRESS INTERNAL USE ONLY Customer Objections to Adopting QDR-IV Over GSI SQ-IIIe “The performance of QDR-IV is overkill” A non-banked, low-cost version with 1334 MT/s RTR and 72 Mb density is available QDR-IV is suitable to support a wide range of networking line cards performance (100G, 200G and 400G), extending the product life cycle “I am using GSI SQ-IIIe now. QDR-IV is not pin-to-pin compatible with GSl” GSI SQ-IIIe is not pin compatible with any similar product in the market QDR-IV is a standardized product, which is pin compatible with any other Consortium-defined product Once customer start using QDR-IV, they don’t need to worry about device migration in the future

Sales Training 3/13/ Cypress Confidential Owner : LUOS CYPRESS INTERNAL USE ONLY Sales Cautions for QDR-IV QDR-IV may not be competitive as a packet buffer Packet buffers require low RTR (less than 600 MT/s) and low cost/Gb; therefore QDR-IV is overkill and not justified QDR-IV can serve multiple roles QDR-IV provides up to 2130 MT/s RTR, which satisfies statistics/states, scheduler and lookup applications
