  1. Dynamic random access memory (DRAM) is the most frequently used form of memory in most computers. A DRAM configuration sends a charge through a bitline column of a memory chip's grid configuration and activates a transistor at each appropriate intersection. In writing mode, row lines contain a data-value designated for the capacitor at each intersection. In reading mode, a sense amplifier takes a reading of the charge level in each capacitor. If the level is greater than 50 percent, the capacitor reads as a 1, but if it's less than that, the value is a 0.
