Rough Draft Notes - Work In Progress!
Flash Memory today allows us to do
more than Boot a PC from a Bios Chip. Flash Memory
today can be a Memory Chip Data Storage Device that can be rewritten
quickly and hold its content without power. It is widely used for Digital
Film, MP3's, Computer Data Storage and Hand Held Devices such as Cell
Phones. The term was coined by Toshiba for its ability to be erased
"in a flash."
FLASH also known as FEPROM is one of the
newest types of non-volatile memory. In this device, data is erased and
reprogrammed in blocks, unlike the byte by byte altering capability of
EEPROM. FLASH memory has the density of EPROMs and the electrical
erase capability of standard EEPROMs. FLASH is used in digital
cameras to store pictures, PC's store their BIOS on FLASH memory chips,
and MP3 audio recorders use FLASH to store music.
Flash Memory Chips are also conveniently
packaged as "Flash Cards" and come in several formats, including
full-size PC Card (ATA PC Card), smaller CompactFlash (Invented by SanDisk),
Memory Stick and similar formats listed below. Although functionally
similar, none of them are plug compatible. Thank you Manufacturers!

Card - The xD-Picture Card is a new type of ultra-compact memory
media that has been developed jointly by Fujifilm and Olympus. It
meets the demands of new camera technologies that deliver larger image
files and in some cases have the ability to record high-quality movie
footage. By adopting a very small footprint (of only 20 x 25 x 1.7mm
and around 2g in weight), camera designers also have the flexibility
to produce more compact and innovative models.
