Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following memories uses one transistor and one capacitor as basic memory unit?
A
SRAM
B
DRAM
C
Both
D
None
Explanation: 

Detailed explanation-1: -The memory that uses one transistor and one capacitor as a basic memory unit is a DRAM. In a DRAM, a capacitor is used to store a bit of data along with a MOSFET (transfer device) which acts as a switch.

Detailed explanation-2: -DRAM is usually arranged in a rectangular array of charge storage cells consisting of one capacitor and transistor per data bit.

Detailed explanation-3: -DRAM will store bits of data in what’s called a storage, or memory cell, consisting of a capacitor and a transistor.

Detailed explanation-4: -Similar to a microprocessor, a memory chip is an integrated circuit (IC) made of millions of transistors and capacitors. In the most common form of computer memory, dynamic random access memory (DRAM), a transistor and a capacitor are paired to create a memory cell, which represents a single bit of data.
