Computer Architecture Questions Medium
Static RAM (SRAM) and Dynamic RAM (DRAM) are two types of memory used in computer architecture, with each having its own characteristics and advantages.
Static RAM:
1. SRAM is made up of flip-flops, which are stable circuits that can hold data as long as power is supplied.
2. It does not require constant refreshing of data, making it faster and more reliable than DRAM.
3. SRAM has lower access times and latency, allowing for faster data retrieval.
4. It is more expensive and consumes more power compared to DRAM.
5. SRAM is commonly used in cache memory and registers, where speed and reliability are crucial.
Dynamic RAM:
1. DRAM uses capacitors to store data, which require constant refreshing to maintain the stored information.
2. It is less expensive and more compact compared to SRAM.
3. DRAM has higher storage density, allowing for larger memory capacities.
4. It consumes less power compared to SRAM.
5. However, DRAM has higher access times and latency due to the need for refreshing, making it slower than SRAM.
6. It is commonly used as main memory in computers due to its cost-effectiveness and high capacity.
In summary, the main difference between SRAM and DRAM lies in their speed, reliability, cost, power consumption, and usage. SRAM is faster, more reliable, expensive, and power-hungry, while DRAM is slower, less reliable, cheaper, and power-efficient.
