Capacitance balancing in semiconductor devices

A method, comprising:

• receiving, by a target local sense line, a first current, wherein the target local sense line is coupled to a target global sense line;
• applying the first current to a memory cell in a stack of memory cells coupled to the target local sense line to select the memory cell;
• determining a sum of a capacitance of the target local sense line and a capacitance of the selected memory cell;
• based on the sum, determining a quantity of reference local sense lines to apply a second current to;
• and
• applying, by a plurality of second drivers coupled to each of the quantity of reference local sense lines, the second current to each of the quantity of the reference local sense lines.
