摘要：
A memory array device with an embedded self-test binary pattern. The device has an array of bistable cells formed with first and second sides that are oppositely connected to a first voltage line or a second voltage line. If the first and second voltage lines are energized at the same voltage level, each of the bistable cells will function in a normal bistable mode. If the first and second voltage lines are energized at different levels, each of the bistable cells will function in an embedded binary pattern mode.
