Abstract: An economic efficiency estimation apparatus derives an approximate curve of an initial open-end voltage function and an initial impedance function, sets a prior estimation function, and measures a charge-discharge voltage and a charge-discharge current. The apparatus estimates state parameters including an SOC value, and a polarization voltage and an internal impedance using a Kalman filter. The apparatus obtains an estimation error, calculates a posterior estimation value by a correction expression, corrects the prior estimation function based on the posterior estimation value, sets a new prior estimation function, estimates a charge-discharge curve, and estimates an economic efficiency index based on a charge-discharge power amount estimated from the curve.

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.
