An electrically programmable logic device (EPLD) is a type of programmable logic device (PLD) with an array of initially unconnected programmable logic devices. This type of PLD needs its array of logic devices to be configured or programmed by the user electrically. PLDs are used to build reconfigurable devices that can be used in a variety of applications depending on their programming.
Electrically programmable logic devices have an undefined function when they are manufactured. This is unlike logic gates, which already have a defined set of functions.
Techopedia Explains Electrically Programmable Logic Device
Electronically programmable logic devices are a type of PLD that are not yet configured or programmed for a specific purpose. This means that they come as a blank slate, which the user can use as a base in order to create a logic device with a specialized purpose. The advantage of this is that there is no prior programming that gets in the way; the downside is that it could take a little more time for the device to become usable because it will need to be programmed first.
