Dynamic RAM or DRAM
Dynamic RAM is a form of volatile memory.
It uses the charge of a capacitor to store one bit of data.
DRAM is relatively cheap but unfortunately capacitors leak away their charge and so they need to be topped up every few milliseconds with a refresh signal, hence the word 'dynamic' to reflect this constant need to be refreshed.
DRAM is the most popular technology for main memory. Its counterpart is SRAM or Static RAM
