This disclosure relates to the field of semiconductor technology, providing a memory and its operating method to mitigate the damage caused by row hammer attacks. The memory includes a memory array and a control circuit. The control circuit is configured to, upon meeting preset conditions, respond to a command address signal and a mode control signal to enter a first mode, whereby it begins updating the count memory cell corresponding to the active word line at a first moment, and begins pre-charging the active word line at a second moment, using the count data as the count value for row hammer refresh; or, upon not meeting preset conditions, respond to the command address signal and the mode control signal to enter a second mode, whereby it does not perform an update operation on the count memory cell corresponding to the active word line, and begins pre-charging the active word line at a second moment, using the activation count value of the active word line in a dynamic lookup table as the count value for row hammer refresh. This achieves a balance between flexible configuration and reliability assurance, mitigating the damage caused by row hammer attacks.

This invention discloses a mycotoxin biological antidote, its preparation method, and its application. The preparation method of the mycotoxin biological antidote includes: using *Aspergillus niger* (accession number CGMCC3.4523) as the strain, performing solid-state fermentation to obtain a *Aspergillus niger* solid culture; mixing the *Aspergillus niger* solid culture with glycyrrhizic acid at a mass ratio of 1-3:1-3 to obtain the mycotoxin biological antidote. Using broiler feeding experiments and serum metabolomics analysis, it was demonstrated that the mycotoxin antidote of this invention can effectively alleviate the harm of various mycotoxins to young broilers by regulating the metabolic pathways in serum, thus improving the health of broilers.

The invention discloses a composition for reducing the harm of deoxynivalenol to the immune function of offspring chickens, and is characterized in that the composition comprises the following components: a momordica grosvenori extract, a cinnamon extract, an origanum vulgare leaf extract and functional polypeptide, the mass ratio of the fructus momordicae extract to the cortex cinnamomi extract to the origanum vulgare leaf extract to the functional polypeptide is (1-5): (1-2): (1-2): (1-2). According to the invention, the combination of the natural plant extract and the functional polypeptide is screened, and the combination and the vaccine are injected together during embryo injection immunization, so that the harm of the residual DON in the hatching egg to the immunization of the broiler chicken is relieved, and meanwhile, the adverse effects of an inactivator in the vaccine and an embryo injection mode on the hatching egg are reduced, so that the titer of the vaccine is further improved.
