DRAM (Dynamic Random Access Memory)

1. Structure and Function: DRAM stores data in a cell made of a capacitor and a transistor. It requires periodic refreshing of the data stored in the capacitors, which leaks over time.

2. Speed: Generally slower than SRAM. The need for refresh cycles can slow down access times.

3. Density: Higher density compared to SRAM, meaning it can store more data in the same amount of space.

4. Cost: Less expensive per bit than SRAM, making it suitable for providing high-capacity memory.

5. Power Consumption: Consumes more power than SRAM due to the continuous refresh cycles.

6. Common Uses: Used as the main system memory in computers and other devices due to its cost-effectiveness and high storage capacity.

SRAM (Static Random Access Memory)

1. Structure and Function: SRAM stores data in a cell consisting of four to six transistors. It does not require periodic refreshing to maintain the data.

2. Speed: Faster than DRAM, as it does not require refresh cycles, allowing for quicker access to data.

3. Density: Lower density than DRAM, resulting in less data storage in the same amount of space.

4. Cost: More expensive per bit than DRAM due to its complex structure.

5. Power Consumption: Generally consumes less power than DRAM when idle, as it doesn't need refresh cycles. However, its overall power consumption can be high when active.

6. Common Uses: Often used for cache memory in processors due to its speed, which helps reduce latency and improve performance.
