SUMMARY

The discussion centers on the criteria for choosing between SRAM (Static Random Access Memory) and DRAM (Dynamic Random Access Memory) in various applications. DRAM excels in space efficiency but lags in speed and power consumption due to its refreshing circuitry. In contrast, SRAM offers higher operational speed, making it suitable for cache memory in PCs. Ultimately, the choice between SRAM and DRAM depends on specific application requirements, including speed, power, space, and cost considerations.

PREREQUISITES
  • Understanding of SRAM and DRAM technologies
  • Knowledge of memory hierarchy in computer architecture
  • Familiarity with power consumption metrics in electronic devices
  • Awareness of application-specific requirements for memory selection
NEXT STEPS
  • Research the differences in power consumption between SRAM and DRAM
  • Explore memory hierarchy and its impact on system performance
  • Learn about the role of cache memory in improving processing speed
  • Investigate the cost implications of using SRAM versus DRAM in product design
USEFUL FOR

Engineers, product designers, and computer architects involved in memory selection for electronic devices, as well as students studying computer architecture and memory technologies.

I have always wondered the criteria behind choosing between SRAMs and DRAMs. I know a few of them- like SPEED, POWER, SPACE, etc. But how do we know which one has to be prioritized?

In case of Space, DRAM wins, but loses in Speed of operation. Though DRAMs are less power consuming than SRAMs, the refreshing circuitry adds to the power requirement and makes DRAM more power consuming.
However, the space saving done by DRAM comprehensivley defeats the limitations of this technology!

How do we then decide which one to use in our device? For example, calculators are designed to be compact, yet fast and consume very little power, to the extent that simple dry cells are used to power them! How can we predict the type of RAM used in a calculator based on these?

In the case of a PC, for example, RAMs are DRAMs, but cache memories are SRAMs due to the latter's higher operational speed. Does it mean that with SRAM technology, our PCs could have been faster?

And, if DRAMs have outclassed SRAMs in context of Random Access Memory designs of PCs, what is the limitation that limits their total supremacy over SRAMs? Is it just speed? Or is there some other limitation as well?

Sure, there are many properties. Speed, cost, non-volatility. You compare the properties to the application and make a choice. That's the same in any field, not just computers. How does a trucking company decide on the mix of truck types to buy?
