24 History Flash memory (both NOR and NAND types) was invented by Dr. Fujio Masuoka while working for Toshiba in According to Toshiba, the name "flash" was suggested by Dr. Masuoka's colleague, Mr. Shoji Ariizumi, because the erasure process of the memory contents reminded him of a flash of a camera. Dr. Masuoka presented the invention at the IEEE 1984 International Electron Devices Meeting (IEDM) held in San Francisco, California. Intel saw the massive potential of the invention and introduced the first commercial NOR type flash chip in Copyright 2007 ATP Electronics, Inc. All rights reserved. Page 24

26 Standard Flash Architecture for Nor & Nand flash (in physical) Nor Flash Architecture (in physical).. Nand Flash Architecture (in physical). *This difference( cell connection) will make NOR allows randomaccess for reading. NAND allows only block access. And the Nand flash s capacity will be always larger than nor flash can offer. Copyright 2007 ATP Electronics, Inc. All rights reserved. Page 26

31 Manufacture Process 封裝製程 SIP (System In Package) A hybrid technology that mounting an unpackaged silicon die directly onto the substrate by flying gold wires. It contains a few bare chips, for example Nand flash and controller dies per package to construct one system, and the dies can be arranged either side-by-side or stacked on top of each other. It is a die level processing. And provide system a complete packaging solution. SMT( Surface Mount Technology) The process of assembling printed circuit boards with packaged components soldered to the surface rather than to plated through-holes.

32 SIP 工業等級封裝製程 Complete encapsulation and protection of the flash components and contacts. Complete to isolated all components with real 100% of water proof, ESD proof, Shock proof and Dust proof Reliable & Stabile in higher densities of major form factor memory cards such as CF, SD, microsd and minisd. More consistent yield (more exact and physically consistent cards). Copyright 2007 ATP Electronics, Inc. All rights reserved. Page 32

34 Runtime bad block & Life Cycle NAND flash is intrinsic to be certainly increase bad block during System Operation ATP SIP can do much better protection than SMT ATP industrial grade using top grade level industrial components with wear leveling algorithms technology to extend memory lifetime Life Cycle : SIP > SMT Maximal of each flash Memory Card bad block is 2% only ( Initial bad block + Runtime bad block ) Copyright 2007 ATP Electronics, Inc.
