1 NON-VOLATILE SOLID STATE RECORDING Doyle Johnson Mountain Optech Inc Walnut St, Suite A Boulder CO Phone: ; FAX: doyle@mt-optec.com Presented at the THIC Meeting in Marriott Denver Southeast July 22, 1997
2 Mountain Optech Designs, Manufactures and Markets Rugged Mass Memory Solutions
3 COMPANY BACKGROUND Founded in 1985 Located: Boulder, Colorado Products: Mass Memory Systems Specialty: Rugged COTS Products Optical MO & CD-ROM Magnetic Hard Drives Solid State Subsidiary of Phillips Service Industries, Inc. General Manager: Dennis Sauerbrey
4 DEVELOPMENT MOUNTAIN OPTECH INC., MID 1994 WE NEED A HIGH CAPACITY NON- VOLATILE SOLID STATE DATA STORAGE PRODUCT
5 WHY FLASH SOLID STATE Extremely Durable Under Harsh Conditions Wide Temperature Range - 40 to +75 C No Rotating Media / No Moving Parts Fast Data Accesses Microseconds Instead of Milliseconds No Latency Secure Data Non-Volatile
6 WHAT IS MASS STORAGE FLASH Custom Boards With Captive Memory Chips EEPROM, NOR, DINOR New Design Required For Upgrade Socketed Flash ( Intel, AMD, Micron) Bulk/Sectored/Boot Block (64K Blocks) Requires Driver or FTL (Flash Translation Layer) Hard Disk Emulation FLASH Modules Byte Sectors With IDE/ATA Interface SanDisk, Hitachi, Mitsubishi, Smart Modular
7 SOLID STATE MINIMUM REQUIREMENTS SCSI II, 1553, RS-422, RS-232 Inputs Special Bus Alternatives 8 Megabytes DRAM Cache Memory 16 Megabytes to 1 Gigabyte Non-Volatile Flash Memory Multi-Processing Operating System 1 Megabyte Sustained Write Rate (Channel Speed Burst) 2 Megabyte + Sustained Read Rate 810 D Environmental Performance 6 Grms Vibration 30 G Shock -40 to 75 Degrees C Temperatures
8 DEVELOPMENT OBJECTIVE Non-Volatile Solid State Read/Write Data Storage Product Requirements Fast Write/Read Data Rate High Capacity Reliable Long Product/Technology Life Reasonable Cost Versatile Easily Upgradable Growth Path - Building Block Design
9 SOLID STATE PRODUCT DEVELOPMENT Review of Existing Technology Technology was not yet ready for High Capacity Write Rate too Slow Too Costly How Can We Be Ready With the Technology? We Needed a Standard Bus Interface Controller We Need a Device Interface to the Solid State Device
10 INTERFACE CONTROLLER Fall 1994 MOI Awarded Phase II SBIR for Development of an Optical Recorder for Use on V22 Development Requirement: Intelligent Interface Controller
11 FIRST BUILDING BLOCK Intelligent Interface Controller Multiple Input Interfaces - SCSI, 1553, RS 232, RS422 Booch Object Oriented C++ Software CPU Power for the Future - Intel 80CF960 Multi Processing Real Time OS - psos Expandable and Up-dateable ROM - Captive FLASH Data Buffering - 8 MB EDO RAM Standard Device Output - SCSI, PCMCIA-ATA
