Abstract

An electronic device includes a memory having a plurality of memory rows and a memory refresh functional block that performs a victim row refresh operation. For the victim row refresh operation, the memory refresh functional block selects one or more victim memory rows that may be victims of data corruption caused by repeated memory accesses in a specified group of memory rows near each of the one or more victim memory rows. The memory refresh functional block then individually refreshes each of the one or more victim memory rows.
