  1. Sharp Flash Memory What’s flash memory Flash type / Unit / Package How to recognize Sharp flash Flash memory application Sharp flash vs Intel flash Note

  2. What’s Flash memory

  3. Flash Type

  4. NAND type Code Flash Data Flash NOR type Data, Voice, Picture Code, Program Intel, Sharp, AMD, Fujitsu (Spansion), SSI, MXIC Samsung, Toshiba ST Mircom, Hynix

  5. CY2003 Worldwide NOR Flash Memory Quantity Others(20%) Intel(27%) Atmel (3%)　 STMicro (9%) AMD (16%) Sharp (10%) Fujitsu (15%) SHARP Confidential Others(25%) Intel(40%) STMicro (6%) Spansion (Fujitsu+AMD) (19%) Sharp (10%) Actual CY2003 Market Size: 1.1 Billions of Units (64Mb-equivalent) Actual CY2002 Market Size: 0.6 Billions of Units (64Mb-equivalent) SHARP Estimate based on IDC/Dataquest/WSTS, etc.

  6. Sharp – Nor type only ! Boot block type 1.) Every block size different : For different software application 2.) Top boot : Software start from top block Bottom boot : Software start from bottom block Symmetrical type : Every block is the same

  7. Flash unit 1M Byte = 8M bit 2M Byte = 16M bit 4M Byte = 32M bit Note : B = Byte / b = bit

  8. Package

  9. BGA/CSP application – Most for handheld or smaller products For example : Mobile phone, MP3 player DSC, GPS, PDA….. TSOP application – For example : N/B BIOS, Cable/ADSL/VOIP modem, STB,DVD player….

  10. How to recognize Sharp Flash memory

  11. Single chipa. Boot block : LH28FXXXBJ LH28FXXXBF LHF00LXXb. Symmetrical : LH28FXXXS c. LPC interface * : LH00LXX (System-flash) 2. Combo : LRSXXXX 3. Smart card system a/b  Highly (1.8v/3v) and standard function System –flash : Mainly for mobile application (phone,DSC,N/B) * LPC : For non-Intel CPU FWH : For Intel CPU only

  12. Combo Flash – By FBGA/CSP package Boot block flash + SRAM  LRS13XX (Top/bottom) 2. Boot block flash + SCRAM (PSRAM)  LRS18XX (Top/bottom) Boot block flash + SCRAM + SRAM  LRS1BXX (Top/bottom) Boot block flash + SDRAM (New!) LRS14XX (Top/bottom)

  13. Flash memory application

  14. Sharp Flash vs Intel Flash

  15. LH28FXXXBV/BJ/BF  8M~128M LH28F160BJHE LH28F640BFHE LH28FXXXS 64M~128M LH28F640SPT No compatible model LRSXXX  32M~256M (MLC) LRSXXX  32M~256M (Non-MLC) B3/C3 16M,32M TE28FXXXB3XX TG28FXXXC3XX J3 (Strata)  32M~128M (Single chip) K3 (Strata)  64M~256M L30/L18 (Strata)  32M~256M + PSRAM (Combo) W30 / W18 32M~128M Sharp Flash vs Intel Flash

  16. Note 1: When you get a inquiry or find a business chance 1. Application & Spec check : Density, package, top/bottom, access time…. 2. Recommend ongoing model : Single model multi-customers (SMMC) 3. Three key elements for flash business Q’ty , Price , Delivery ,

  17. Note 2: a. Lead free model available b. All flash L/T : 3 months
