SuperFlash® Memory Products High Performance, Low Power Consumption and Superior Reliability What is SuperFlash? SuperFlash is an innovative, highly reliable and versatile type of NOR Flash memory invented by Silicon Storage Technology (SST). SuperFlash memory is much more flexible and reliable than competing non-volatile memories. This technology utilizes a split-gate cell architecture which uses a robust thick-oxide process that requires fewer mask steps resulting in a lower-cost nonvolatile memory solution with excellent data retention and higher reliability. SuperFlash Advantages ■■ Fast, fixed program and erase times • ~ 40 ms vs. more than a minute for 64 Mb • Results in improved manufacturing efficiency and lower costs ■■ No pre-programming or verify required prior to erase • Results in significantly lower power consumption ■■ Superior reliability • 100K cycles and 100 years data retention ■■ Inherent small sector size • 4 KB erase sector vs. 64 KB • Results in faster re-write operations and contributes to lowering overall power consumption Memory Cell Structure Comparison Poly 2 Poly 1 Thicker tunnel oxide reduces leakage improving data retention and reliability. Source Split Gate Drain SuperFlash ® Poly 2 Poly 1 Source Stacked Gate (Conventional Flash) Drain Time Is Money Fast erase performance improves manufacturing efficiency and lowers product costs! With stacked gate Flahs, extensive production testing can slow down the manufacturing flow, costing more money. SuperFlash can lower test and/or programming costs by as much as $0.32 per unit*. * Based on 64 seconds × US $0.005 per second = US $0.32 per unit. 64 seconds is the typical chip erase time for our competitors’ 64 Mb device. Our 64 Mb device maximum chip erase time is 50 ms. Multi-Purpose Flash Plus (MPF+) Fast Erase Performance Improves Manufacturing Efficiency and Lower Costs!
