Dynamic RAM is the most common type of memory in use today. Inside a dynamic RAM chip, each memory cell holds one bit of information and is made up of two parts: a transistor and a capacitor. These are, of course, extremely small transistors and capacitors so that millions of them can fit on a single memory chip.

Dynamic RAM (DRAM)
• Dynamic RAM (DRAM) is a type of RAM that stores each bit of data in a separate capacitor within an integrated circuit.
• A capacitor is an electronic component that can store an electrical charge.
• Since capacitors can only hold a charge for a short amount of time, DRAM needs to be refreshed constantly to keep its data intact.
• DRAM is cheaper and denser than its counterpart, static RAM (SRAM), which uses flip-flops to store data.
Structure of DRAM
• DRAM consists of a capacitor and a transistor for each bit of data.
• The capacitor stores the data and the transistor acts as a switch that controls the flow of data in and out of the capacitor.
• The transistor is responsible for reading and writing data to the capacitor.
• The capacitor is made up of two plates separated by an insulating material called a dielectric.
Number of Transistors and Capacitors in DRAM
• The number of transistors and capacitors in DRAM depends on its architecture.
• The most common type of DRAM architecture is the one-transistor, one-capacitor (1T1C) cell.
• In the 1T1C architecture, each bit of data is stored in a single capacitor that is connected to a single transistor.
• Therefore, the correct answer is option 'D' - DRAM consists of 1 transistor and 1 capacitor.
