How does various capacitances vary in dynamic RAM or DRAM?

The DRAM capacitor Ccell must be as physically small as possible to achieve good density. However, the bitline is contacted to many DRAM cells and has a relatively large capacitance Cbit. Therefore, the cell capacitance is typically much smaller than the bitline capacitance. a large cell capacitance is important to provide a reasonable voltage swing. It also is necessary to retain the contents of the cell for an acceptably long time and to minimize soft errors.

How to Calculate Cell Capacitance?

Cell Capacitance calculator uses Cell Capacitance = (Bit Capacitance*2*Voltage Swing on Bitline)/(Positive Voltage-(Voltage Swing on Bitline*2)) to calculate the Cell Capacitance, The Cell Capacitance formula is defined as how quickly the membrane potential can respond to a change in current. A capacitor is made up of two conducting materials separated by an insulator in the case of a cell, the extracellular and intracellular fluids are the conductors, and the lipid membrane is the insulator. Cell Capacitance is denoted by C_cell symbol.
