Abstract
An address refresh check method includes: setting a row address with a highest repetition rate or with a quantity of repetition times exceeding a predetermined threshold as a seed address, and determining an address type; if the address type is a random address, obtaining an expected refresh address; performing a row hammer refresh operation to obtain an actual refresh address; and comparing the expected refresh address with the actual refresh address to obtain a check result.
