![]() ![]() In the designs where a capacitor is used, the capacitor can either be charged or discharged these two states are taken to represent the two values of a bit, conventionally called 0 and 1. While most DRAM memory cell designs use a capacitor and transistor, some only use two transistors. ![]() Motherboard of the NeXTcube computer, 1990, with 64 MiB main memory DRAM (top left) and 256 KiB of VRAM (lower edge, right of middle).ĭynamic random-access memory ( dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology. ![]()
