Memory test systems provide programmable timing generators with fine edge placement resolution, allowing accurate characterization of access times, hold times, and setup windows. Parametric measurement units can force voltages and measure currents at pins, enabling leakage tests, DC parameter measurements, and voltage-level verification. The exact performance range varies across models and options, but these capabilities are fundamental to the class.
Many memory test systems are designed with modular architectures that allow them to switch between wafer probe and final test by exchanging hardware interfaces (e.g., probe card adapter versus handler dock). However, the core test electronics remain the same. Some systems offer parallel test capability for multiple DUTs, and the overall throughput depends on the configuration and test program complexity.
