Original Abstract Submitted
methods, systems, and devices for retiring pages of a memory device are described. an ordered set of device information pages may be used to store device information. the device information pages may be in non-volatile memory. each page may include a counter value of the number of accesses to indicate if the page includes valid data. a flag associated with the page may be set when the counter value reaches a threshold, to retire the page. upon power-up, the device may determine which page to use, based on the flags. the flag may be stored in the page, or may be separate (e.g., fuse elements). if fuse elements are used, the page may store a programming-in-process flag to indicate when programming of the fuse element may not have been completed before power loss, in which case the programming may be restarted after power is restored.
