Abstract:
A stacked memory is disclosed including a first integrated circuit memory chip having first storage locations and a second integrated circuit memory chip disposed in a stacked relationship with the first integrated circuit memory chip. The second integrated circuit memory chip has second storage locations. Redundant storage is provided including a first storage area dedicated to storing failure address information of failure address locations in the first or second integrated circuit memory chips. The redundant storage includes a second storage area dedicated to storing data corresponding to the failure address locations. Matching logic matches incoming data transfer addresses to the stored failure address information.
