Why is Static RAM faster than Dynamic RAM. Why is it so expensive to manufacture SRAM?
I’ll attempt an answer to your second question;ramollari said:Why is it so expensive to manufacture SRAM?
Level 1 cache has always been built directly into the processor die and runs at the same speed as the processor itself. Meanwhile, on early boards, the L2 cache was external and ran at the slower (asynchronous) speed of the motherboard. L2 was later built inside the processor chip and finally it was built inside the processor die itself (there is a difference between being those last two). If you do a search for cache memory on ebay you can still see the older, external, motherboard mounted L2 cache for sale and better understand what I’m talking about (it was often replaceable/upgradeable the way main memory is today). There were gains in performance in those evolutions of the L2 but the L1 cache is and always has been the ‘first line of defense’ when it comes to anticipating what data the processor is going to need next.Why is Level1 Cache faster than Lever2 Cache? Both use the Static RAM technology.
Which level cache is measured as a parameter of CPUs?
The main difference between static and dynamic RAM is the way they store data. Static RAM (SRAM) uses a flip-flop circuit to store each bit of data, while dynamic RAM (DRAM) uses a capacitor and transistor to store data.
Static RAM is faster than dynamic RAM because it does not require refreshing to maintain the data. SRAM can access data in a few nanoseconds, while DRAM takes longer due to the need for refreshing.
Static RAM is more expensive because it requires more transistors to store each bit of data, making it more complex and costly to manufacture. Additionally, static RAM is typically used in specialized applications where speed is crucial, while dynamic RAM is used in more general-purpose applications.
Yes, it is common for computer systems to use both static and dynamic RAM. Static RAM is often used for cache memory, which is faster and more expensive than DRAM, while dynamic RAM is used for the main memory to store larger amounts of data at a lower cost.
The difference in cost and speed between static and dynamic RAM determines where each type is used in a computer system. Static RAM is typically used for cache memory and small amounts of high-speed memory, while dynamic RAM is used for the main memory of a computer system due to its lower cost per bit of storage.
