Abstract: Aspects of the present disclosure configure a memory sub-system controller to selectively adjust a program pulse for different word line groups of a memory sub-system. The controller receives a request to program data to an individual memory component of a set of memory components. The controller determines that a program erase count (PEC) associated with the individual memory component transgresses a threshold value. The controller, in response to determining that the PEC associated with the individual memory component transgresses the threshold value, selectively adjusts a predetermined program voltage (Vpgm) associated with a subset of word lines (WLs) of the individual memory component based on whether the subset of WLs is associated with an individual WL group (WLG). The controller programs the data to the individual memory component according to the selectively adjusted predetermined Vpgm.

Abstract: A method for combined characterization of pore structure includes steps as follows. Firstly, CO2, N2 and high-pressure mercury intrusion porosimetry characterization curves are plotted based on actual measurement data, then, average values of the overlapping range of the CO2 and N2 characterization curves are calculated, and a function yi?=ƒ(x) is fitted. Each pore volume yi? corresponding to each pore diameter xi is calculated, and a curve is plotted with xi as a horizontal coordinate and yi? as a vertical coordinate, thereby obtaining a characterization curve of the overlapping range between CO2 and N2 adsorptions. The same data processing is used to process the overlapping range data of the N2 and high-pressure mercury intrusion porosimetry characterization curves, to obtain the characterization curve between them. The characterization curves are spliced with the original CO2, N2, and high-pressure mercury intrusion porosimetry characterization curves to obtain a combined characterization curve.
