Removable mother/daughter peripheral card

A method of employing a solid state memory system including flash EEPROM, comprising:

• utilizing a card including flash EEPROM without a controller function therefor being included within the card and a mother unit including a first controller providing said controller function, wherein the card is electrically and mechanically removably connectable with said mother unit through a first type of interface, the flash EEPROM operating with the first controller of the mother unit when so connected,
• electrically and mechanically connecting the card through the first type of interface directly to a first host system without use of said mother unit, wherein the controller function is provided by a second controller embedded within the first host system,
• operating the first host system to transfer data between the first host system and the flash EEPROM of the card through the second controller,
• removing the card from connection with the first host system,
• electrically and mechanically connecting the mother unit directly with a second type of interface of a second host system that does not include the controller function embedded therein, said first and second types of interfaces being different from each other,
• electrically and mechanically connecting said card directly with the mother unit through the first type of interface, and
• operating the second host system to transfer said data between the second host system and the flash EEPROM of the card through the first controller,
• thereby to exchange said data between the first and second host systems through the use of the card.

• electrically and mechanically connecting the card through the first type of interface directly to a camera without use of said mother unit, wherein the controller function is provided by a second controller embedded within the camera,
• recording a visual field by the camera as data in the flash EEPROM of the card through the second controller,
• removing the card from connection with the camera,
• thereafter electrically and mechanically connecting the mother unit directly with a second type of interface of a host system that does not include the controller function embedded therein, said first and second types of interfaces being different from each other,
• electrically and mechanically connecting said card directly with the mother unit through the first type of interface, and
• operating the host system to transfer said data between the second host system and the flash EEPROM of the card through the first controller,
• whereby the visual field recorded by the camera may be viewed.
