Dynamic random-access memory (DRAM) Dynamic random-access memory (DRAM) is a type of random-access memory that stores each bit of data in a s eparate capacitor within an integrated circuit. The capacitor can be either charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1. DRAM is the memory we use as physical memory that helps the PC/laptop to run applications. A DRAM storage cell is dynamic in that it needs to be refreshed or given new electronic charges every few milliseconds to compensate for charge leaks from the capacitor. example PC/laptop it has 2GB of RAM. Static random-access memory (SRAM) SRAM (static RAM) is random access memory (RAM) that retains data bits in its memory as long as power is being supplied . SRAM does not have to be periodically refreshed . example of SRAM is SRAM is used as cache memory.
