WebJan 10, 2024 · Data read from DRAM or persistent memory is transferred through the memory controller into the L3 cache, then propagated into the L2 cache, and finally the L1 cache where the CPU core consumes it. When the processor is looking for data to carry out an operation, it first tries to find it into the L1 cache. WebHowever, SRAM is also more expensive than DRAM, and it requires a lot more space. SRAM is commonly used for a computer's cache memory, such as a processor's L2 or L3 cache. It is not used for a computer's main memory because of its cost and size. Most computers use DRAM instead because it supports greater densities at a lower cost per …

WebApr 12, 2024 · DRAM, which is also known as Dynamic Random Access Memory, is a widely used type of RAM. It’s a memory chip that can hold large amounts of data but requires a lot of power. SRAM, or Static Random Access Memory, is also a memory chip. It uses less power and offers better performance when compared to DRAM.
