What is Dynamic RAM? |
|
Answer» DRAM is also a volatile memory that uses separate capacitors to store each bit. Capacitors, when not charged, represent the value 0 of a bit and when charged represent the value 1. Since the capacitors discharge with time, they need to be refreshed periodically to maintain the values stored in them. Each memory cell in a DRAM consists of a capacitor and a transistor and these cells are arranged in a square array. |
