EEPROM (electrically erasable programmable read-only memory) is
user-modifiable read-only memory (
ROM)
that can be erased and reprogrammed (written to) repeatedly through the
application of higher than normal electrical voltage. Unlike
EPROM chips, EEPROMs do not need to be removed from the computer to
be modified. However, an EEPROM chip has to be erased and reprogrammed
in its entirety, not selectively. It also has a limited life - that is,
the number of times it can be reprogrammed is limited to tens or
hundreds of thousands of times. In an EEPROM that is frequently
reprogrammed while the computer is in use, the life of the EEPROM can be
an important design consideration.
A special form of EEPROM is
flash memory, which uses normal PC voltages for erasure and
reprogramming.

IDE (Integrated Drive Electronics) is a standard electronic
interface used between a computer
motherboard's data paths or
bus and the computer's disk storage devices. The IDE interface is
based on the IBM PC Industry Standard Architecture (ISA)
16-bit
bus standard, but it is also used in computers that use other bus
standards. Most computers sold today use an enhanced version of IDE
called Enhanced Integrated Drive Electronics (EIDE).
In today's computers, the IDE controller is often built into the
motherboard.
