What is the primary reason that **Dynamic Random Access Memory (DRAM)** requires periodic refreshing?

Question

Accepted Answer

**Solution:**

1. DRAM stores each bit of data in a tiny capacitor paired with a transistor.

2. These capacitors gradually lose their electrical charge over time, typically within milliseconds.

3. If the charge is not replenished regularly, the stored data will be lost.

4. Therefore, DRAM requires periodic refreshing to recharge these capacitors and maintain the integrity of the data.

5. This refresh operation is handled automatically by the memory controller and is transparent to the user.

6. Other options such as preventing magnetic field corruption, clearing unused data, or enabling CPU access are not the primary reasons for refreshing.

**Answer:** To recharge the capacitors storing data bits
