Abstract
Provided are a method for controlling a row hammer and a memory device. The memory device includes: a memory cell array having memory cell rows; a control logic circuit configured to classify access addresses of the memory cell array as real and fake entries, and identify a row hammer address from among the access addresses; and a refresh control circuit configured to refresh a memory cell row physically adjacent to a memory cell row indicated by the row hammer address during a row hammer monitoring time frame. The control logic circuit is further configured to promote a fake entry to a real entry based on the number of accesses of the fake entry being equal to or greater than a first threshold.
