Abstract
A semiconductor device includes an error count signal generation circuit and a row error control circuit. The error count signal generation circuit generates an error count signal which is enabled if the number of erroneous data of cells selected to perform an error scrub operation is equal to a predetermined number. The row error control circuit stores information concerning the number of the erroneous data in response to the error count signal if the number of the erroneous data is greater than or equal to the predetermined number or stores information concerning the number of row paths exhibiting the erroneous data in response to the error count signal after more erroneous data than the predetermined number is detected.
