Hello, I would like to know what kind of electrical signals does a cpu send to a dynamic RAM when it wants to write one bit (a 1 or 0).

Is it simply that cpu sends just a single electric pulse, and if that electric pulse's voltage is higher than a certain level, it charges the capacitor to a voltage level that is "1" and if it is at a lower voltage band, it charges capacitor to level that it is "0"?
