DRAM:
Dynamic Random Access Memory (DRAM) is a type of memory that is mainly used in computers and other electronic devices. DRAM is named dynamic because it requires periodic modification and activity to retain data.
SRAM:
Static Random Access Memory (SRAM) is a type of memory that is mainly used in computers and other electronic devices. It doesn’t need to be periodically refreshed to retain its data, making it a faster and more reliable form of memory.
