Static RAM (SRAM)

None of the above

Detailed explanation-1: -A DRAM storage cell is dynamic, meaning that it needs to be refreshed or given a new electronic charge every few milliseconds to compensate for charge leaks from the capacitor.
Detailed explanation-2: -Delay-line memory requires constant refreshing because the data is actually stored as a signal in a transmission line.
Detailed explanation-3: -Pronounced DEE-RAM, DRAM is widely used as a computer’s main memory. Each DRAM memory cell is made up of a transistor and a capacitor within an integrated circuit, and a data bit is stored in the capacitor.
Detailed explanation-4: -This refresh process is the defining characteristic of dynamic random-access memory, in contrast to static random-access memory (SRAM) which does not require data to be refreshed. Unlike flash memory, DRAM is volatile memory (vs. non-volatile memory), since it loses its data quickly when power is removed.
