This required considerable computer support, and PC-based EEPROM flash memory systems often carried their own dedicated microprocessor system.Flash drives are more or less a miniaturized version of this.Hardware designers later developed EEPROMs with the erasure region broken up into smaller "fields" that could be erased individually without affecting the others.Altering the contents of a particular memory location involved copying the entire field into an off-chip buffer memory, erasing the field, modifying the data as required in the buffer, and re-writing it into the same field.The USB connector may be protected by a removable cap or by retracting into the body of the drive, although it is not likely to be damaged if unprotected.Most flash drives use a standard type-A USB connection allowing connection with a port on a personal computer, but drives for other interfaces also exist.They are smaller, faster, have thousands of times more capacity, and are more durable and reliable because they have no moving parts.
A flash drive consists of a small printed circuit board carrying the circuit elements and a USB connector, insulated electrically and protected inside a plastic, metal, or rubberised case, which can be carried in a pocket or on a key chain, for example.
and had a storage capacity of 8 MB, more than five times the capacity of the then-common 3½-inch floppy disks (of 1440 KB).
In 2000, Lexar introduced a Compact Flash (CF) card with a USB connection, and a companion card read/writer and USB cable that eliminated the need for a USB hub.
The memory storage was based on earlier EPROM and EEPROM technologies.
These had limited capacity, were slow for both reading and writing, required complex high-voltage drive circuitry, and could be re-written only after erasing the entire contents of the chip.
