Abstract
Integrated circuit devices are provided including first and second chips and a common input/output pad electrically coupled to the first and second chips. At least one of the first and second chips includes a high voltage generator configured to receive an input voltage through the common input/output pad and generate a test voltage responsive to a test mode signal during a test mode of operation. The test voltage is higher than the input voltage. Related methods of operating integrated circuit devices and semiconductor devices are also provided.
