Abstract
A memory system including a memory device. The memory device includes a substrate. A memory array defines a plurality of pages, each page including a data area for storing data and a spare area for storing metadata. A compare circuit is configured to receive metadata retrieved from a plurality of pages sequentially and compare the retrieved metadata to a search pattern. The physical location of the page can be determined by finding the search pattern. The memory array and the compare circuit are formed in different layers of the substrate.
