Circuits, architectures, apparatuses, systems, methods, algorithms, software and firmware for using reserved cells to indicate defect positions

摘要

A system including a plurality of data storage cells, where each of the plurality of data storage cells is configured to store a plurality of data bits, and a plurality of reserved cells configured to store status information of one or more of the plurality of data storage cells. Each of the plurality of reserved cells includes a multi-bit cell configured to store the status information at a lower density than each of the data storage cells.
