Abstract:
A multi-chip stacked system and a chip select apparatus are provided. The chip select apparatus includes n ID code generators and n activation logic units. The first ID code generator generates a first ID code and a second seed code according to a first seed code, and an ith ID code generator connected to the (i−1)th ID code generator generates an ith ID code and an (i+1)th seed code according to the ith seed code. The ID codes generated by the ID code generators are different to each other. Each of the activation logic units has an activation code. The ith activation logic unit receives the ith ID code from the ith ID code generator. The ith activation logic unit activates the ith chip when the ith ID code is complied with the activation code of the ith activation logic unit.
