Dram charge sharing
WebNov 21, 2024 · DRAM is based on a stacked capacitor architecture, where the capacitor is connected and resides over a recessed channel array transistor structure. The … Web5.5.2 Dynamic Random Access Memory (DRAM) DRAM, pronounced “dee-ram,” stores a bit as the presence or absence of charge on a capacitor. Figure 5.46 shows a DRAM bit cell. The bit value is stored on a capacitor. The nMOS transistor behaves as a switch that either connects or disconnects the capacitor from the bitline.

WebThe charge (Q) stored in a capacitor is equal to capacitance times voltage (Q = C x V). Over the years, DRAM operating voltage has decreased (i.e., 12V to 5V to 3.3V). As voltage decreases, the stored charge will also decrease. Design improvements allow for the decrease in the cell charge as long as the capacitance remains in the range of 30fF.
