Integrated Drive Electronics (IDE) surfaced in 1988 when a number of vendors formed the Common Access Method Committee, originally to standardize a SCSI software interface. As part of their efforts the outcome was the AT Attachment (ATA), which became associated with IDE. IDE drives have most of the controller functions as part of the circuit board attached to the hard drive. The 40-pin connector is now standardized for most system boards and the IDE hard drive. Because of the logic, or intelligence being moved to the hard drive, it is sometimes called Intelligent Drive Electronics.
