1 PC Card ATA command Extensions for Small Memory Card MEI(Panasonic), SanDisk,Toshiba Minoru Patrick Ohara(Toshiba)

2 MEI,SanDisk,TOSHIBA 2 Agenda Update Update Purpose Purpose Overview Overview Market Impact Market Impact Proposal Plan Proposal Plan Technical Overview Technical Overview Commands Commands Command Example for SD Card Command Example for SD Card Comparison with IBM proposal Comparison with IBM proposal Goal Goal

3 MEI,SanDisk,TOSHIBA 3 Update from Last meeting  Consider the modification with IBM Discussion with IBM Clarification for Both Proposals  Put Overview Modify the Document  Decrease commands Delete D5 and D6

4 MEI,SanDisk,TOSHIBA 4 Proposal Purpose  Define the Commands for ATA adopter for Small Memory Cards Not only for SD,but also SD-IO, SmartMedia, Memory Stick Not only for SD,but also SD-IO, SmartMedia, Memory Stick Common PC Card ATA interface for above Small PC card. Common PC Card ATA interface for above Small PC card. Enable the Generic Driver for SD card /ATA as Storage devices Enable the Generic Driver for SD card /ATA as Storage devices

5 MEI,SanDisk,TOSHIBA 5   Define New Command on ATA Reserved Area (D1 to D4) D1: Switch to Adopter command mode D2-D4:Assign to Media card (Small Memory cards)   Expand the definition of the ATA IDENTIFY DEVICE command on word. Range Proposal Overview Expand the IDE/ATA Commands for PC Card Adopter

6 MEI,SanDisk,TOSHIBA 6 Command pass through the PC Card ATA Command pass through the PC Card ATA – Working as Storage Device on Current System – SD Functions are Enabled by SD command pass through (NOT by CPRM) Common ATA Interface: Controller, Drivers Common ATA Interface: Controller, Drivers Common SD Card Adopter for Note-PC through PC Card Slot Common SD Card Adopter for Note-PC through PC Card Slot Market Impact ATA PC Card Adopter for SD This Proposal Common I/F

7 MEI,SanDisk,TOSHIBA 7 Other Possible Solutions for ATA Adopters by this proposal  SD-IO: Non security  SmartMedia: Serial ID based Security(Non-CPRM)  Memory Stick: Magic Gate(Non-CPRM) /IO  Others Camera Media Card: Small Memory Card

8 MEI,SanDisk,TOSHIBA 8  Design Implementation for ATA Adopter  Working with T13 for D1-D4 Assignment  Working Other Organizations prior D1-D4 assignment PCMCIA/JEIDA for PC card ATA PCMCIA/JEIDA for PC card ATA SDA for SD Based D1-D4 Usage by “SD Command ATA Extension document” SDA for SD Based D1-D4 Usage by “SD Command ATA Extension document” Other Cards: Each Groups Other Cards: Each Groups Proposal Plan

9 MEI,SanDisk,TOSHIBA 9 Technical Overview   Define Commands D1 to D4 in ATA command reserved area. D1: Check Card Extension Commands D1: Check Card Extension Commands D2-D4: Assigned by Each Memory card D2-D4 for SD are descried by “SD ATA Command Extension“   Expand the definition of the ATA IDENTIFY DEVICE command on word.

10 MEI,SanDisk,TOSHIBA 10 Command Packets ATA Command Command Extension for Media Card ATA Command Current This Proposal

11 MEI,SanDisk,TOSHIBA 11 Software Hierarchy (without Security or Current System) File System Generic ATA Driver Host System ATA Controller Media Card (Data Area) Generic ATA Command Card ATA Command

12 MEI,SanDisk,TOSHIBA 12 Software Hierarchy ( Media Card Mode) Security Application ATA Driver Host System ATA Controller Media Card (SD and Others) This Proposal Card Media Card Command Extension Media Card Commands pass through

13 MEI,SanDisk,TOSHIBA 13 Basic Idea ATA Command Mode Media Card Command Mode Command D1h, D2h, D3h, D4h, Command ex. 20h, 30h, 40h, ECh SD Bus Mode ( Transfer State )

14 MEI,SanDisk,TOSHIBA 14 Comparison with IBM proposal

15 MEI,SanDisk,TOSHIBA 15 Application Based Commands ATA Storage vs. ATA Adopters HDD/CF SD Memory SD IO IBM Proposal SD Specification CPRM This Proposal (For PC Card )

16 MEI,SanDisk,TOSHIBA 16 Why the D1-D4 Command is required?  SD IO functionality is needed on the same IF.  SD Command is expanding.  Application can operate with SD API.  Legacy Card support  Possibility for Other Memory cards (SmartMedia, Memory Stick, Others)

17 MEI,SanDisk,TOSHIBA 17 Example for SD Application   Define SD Commands D1 to D4 in ATA command reserved area. D1: Check SD Extension Commands D1: Check SD Extension Commands D2: SD Header Command D3: SD Execute Command D4: Retrieve Response Command   Expand the definition of the ATA IDENTIFY DEVICE command on word.

18 MEI,SanDisk,TOSHIBA 18  Define the ATA Command Extension for Media Card (SD and Others ) by D1-D4 Initiate the Media Card Application on PC card Slot Initiate the Media Card Application on PC card Slot Common Switching Mechanism in PC Card ATA Common Switching Mechanism in PC Card ATA Common interface for other Media cards Common interface for other Media cards  Do command conflict for Current and Future ATA/IDE  SD Command Extensions in SDA Goal

19 MEI,SanDisk,TOSHIBA 19 Conclusions  Purpose: PC Card ATA adopters for Media Card  D1-D4 :ATA Command Are requirement D1: For Switching the Mode D1: For Switching the Mode D2-D4: Assign to Media Card commends D2-D4: Assign to Media Card commends  Focus on Different Application from IBM Proposal  Independent from CPRM technologies
