FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A dynamic RAM (DRAM) is made with cells that store data as charge on capacitors. The presence or absence of charge in a capacitor is interpreted as a binary 1 or 0. Because capacitors have a natural tendency to discharge, dynamic RAMs require periodic charge refreshing to maintain data storage.

Detailed explanation-2: -Regenerative capacitor memory is a type of computer memory that uses the electrical property of capacitance to store the bits of data.

Detailed explanation-3: -In a DRAM chip, each bit of memory data is stored as the presence or absence of an electric charge on a small capacitor on the chip. As time passes, the charges in the memory cells leak away, so without being refreshed the stored data would eventually be lost.

Detailed explanation-4: -Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology.

Detailed explanation-5: -A DRAM cell is composed of an access transistor and a capacitor. Data is stored in the capacitor as electrical charge, but electrical charge leaks over time. Therefore, DRAM must be refreshed periodically to preserve the stored data. Refresh negatively impacts DRAM performance and power dissipation.
