  • Methods of Operating Semiconductor Memory Devices with Selective Write-Back of Data for Error Scrubbing and Related Devices
    Publication number: 20180246678
    Abstract: A method of scrubbing errors from a semiconductor memory device including a memory cell array and an error correction circuit, can be provided by accessing a page of the memory cell array to provide a data that includes sub units that are separately writable to the page of memory and to provide parity data configured to detect and correct a bit error in the data and selectively enabling write-back of a selected sub unit of the data responsive to determining that the selected sub unit of data includes a correctable error upon access as part of an error scrubbing operation.
