A method of sharing testing components for multiple embedded memories and the memory system incorporating the same

摘要

The present invention relates to a method of sharing testing components for multiple embedded memories and the memory system incorporating the same. The memory system includes multiple test controllers, multiple interface devices, a main controller, and a serial interface. The main controller is used for initializing testing of each of the dissimilar memory groups using a serial interface and local test controllers. The memory system results in reduced routing congestion and faster testing of plurality of dissimilar memories.
