Abstract
Apparatuses including test segment circuits and methods for testing the same are disclosed. An example apparatus includes a plurality of segment lines configured to form a ring around a die and a plurality of test segment circuits, each test segment circuit coupled to at least two segment lines of the plurality of segment lines. Each test segment circuit is coupled to a portion of a first signal line, a portion of a second signal line, and a portion of a third signal line and each test segment circuit is configured to control an operation performed on at least one segment line of the plurality of segment lines.
