US Patent 10468116 Methods of operating a memory device

Methods of operating a memory device include comparing an input address to one or more addresses stored in the memory device and indicative of problematic memory cells of the memory device, determining a status value of an indicator corresponding to a matched address if the input address matches a stored address, and storing data corresponding to the input address to a first memory array of the memory device and to a second memory array of the memory device if the indicator has a first status value. Methods may further include storing the data corresponding to the input address to only the first memory array or the second memory array if the indicator has a second status value.
