SRAM vs DRAM
There are two types of Random Access
Memory or RAM, each has its own advantages and disadvantages compared to
the other. SRAM (Static RAM) and DRAM (Dynamic RAM) holds data but in a
different ways. DRAM requires the data to be refreshed periodically in
order to retain the data. SRAM does not need to be refreshed as the
transistors inside would continue to hold the data as long as the power
supply is not cut off. This behavior leads to a few advantages, not the
least of which is the much faster speed that data can be written and
read.
1. SRAM is static while DRAM is dynamic2. SRAM is faster compared to DRAM
3. SRAM consumes less power than DRAM
4. SRAM uses more transistors per bit of memory compared to DRAM
5. SRAM is more expensive than DRAM
6. Cheaper DRAM is used in main memory while SRAM is commonly used in cache memory
