SEMICONDUCTOR DEVICE AND METHOD OF TESTING SEMICONDUCTOR DEVICE

摘要

A semiconductor device includes chips, wherein a first chip: an internal circuit; first selectors to output signals from one of first outputs; second selectors to output signals from one of second outputs; first output buffer units to relay/interrupt signals output from one of the first outputs; second output buffer units to relay/interrupt signals output from one of the second outputs; first terminals to output a signal from the respective first output buffer units and belong to a first group in which the first terminals are placed at positions distant by first distances; and second terminals to output a signal from the respective second output buffer units and belong to a second group in which the second terminals are placed at positions distant by second distances and each of the second terminals is placed at a position distant from an adjacent first terminal of the first terminals by third distances.
