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 iID code generator connected to the (i−1)ID code generator generates an iID code and an (i+1)seed code according to the iseed 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 iactivation logic unit receives the iID code from the iID code generator. The iactivation logic unit activates the ichip when the iID code is complied with the activation code of the iactivation logic unit.
