Dynamic 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.

DRAM (dynamic random access memory) is a type of semiconductor memory that is typically used for the data or program code needed by a computer processor to function.

Aug 1, 2019 · This article will examine the basic operation of Dynamic Random Access Memory (DRAM), along with how a DRAM chip is organized.

Apr 2, 2021 · DRAM stands for “dynamic random access memory,” and it’s a specific type of RAM (random access memory). All computers have RAM, and DRAM is one kind of RAM we see in modern desktops and laptops. DRAM was invented in 1968 by Robert Dennard and put to market by Intel® in the ‘70s.

Feb 14, 2023 · DRAM, or Dynamic Random Access Memory, is a temporary memory bank for your computer where data is stored for quick, short-term access. When you perform any task …

May 12, 2022 · DRAM stands for dynamic random access memory and is a type of semiconductor memory seen in RAM and GPUs (aka graphics cards). DRAM memory works by storing bits of data in a capacitor inside an ...

Jun 13, 2018 · In 1967, IBM filed for a patent on my single-transistor dynamic random access memory, which became known as DRAM. The patent (Fig. 1) was issued in 1968. In 1970, Intel built the first...

Dec 10, 2002 · Every DRAM chip is equipped with pins (i.e., very short wires), each one of which connects the DRAM to one of many possible bus-ses. Each bus is a group of wires that carry electrical signals; busses connect the CPU, memory controller, and DRAM chips.

Feb 25, 2025 · Dynamic random access memory (DRAM) chips are single-transistor memory cells that use small capacitors to store each bit of memory in an addressable format that consists of rows and columns. Because capacitors are unable to hold a charge indefinitely, DRAM memory chips require a near-constant pulse of current to retain stored information.

Feb 18, 2025 · Current DRAM chips belong to the ’10-nm class’ (denoted as D1x, D1y, D1z, D1a…), where the half pitches of the active area in the memory cell array range from 19 nm down to 10 nm. However, the AI-driven demand for better performing and larger capacity DRAM is propelling R&D into beyond 10-nm generations.
