Dynamic random-access memory - Wikipedia
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.
Introduction to DRAM (Dynamic Random-Access Memory)
2019年8月1日 · Dynamic random access memory, or DRAM, is a specific type of random access memory that allows for higher densities at a lower cost. The memory modules found in laptops and desktops use DRAM. Other types of memory like SRAM, MRAM, and Flash may be discussed in a future article.

DRAM Design Overview
・Passive 1Tr1C cell leads all the features of dynamic circuits and design complexity. The row circuits is fully different from SRAM. because of both the technology saturation and the narrow band-width itself. for the coming embedded era.
since DRAM’s inception, there have been a stream of changes to the design, from FPM to EDO to Burst EDO to SDRAM. the changes are largely structural modifications -- nimor -- that target THROUGHPUT. FPM aallows you to keep th esense amps actuve for multiple CAS commands ...

The Memory Wall: Past, Present, and Future of DRAM
2024年9月3日 · DRAM Primer: Basic Architecture. In principle, DRAM is simple. It comprises an array of memory cells laid out in a grid, each storing one bit of information. All modern DRAM uses a 1T1C cell, denoting 1 transistor and 1 capacitor.
2002年12月10日 · DRAM is the “computer memory” that you order through the mail or purchase at Best Buy or CompUSA. It is what you put more of into your computer as an upgrade to improve the computer’s perfor-mance.
What is DRAM (Dynamic Random Access Memory)? How Does it …
DRAM is a common type of random access memory (RAM) that is used in PCs, workstations and servers. Random access allows the PC processor to access any part of the memory directly rather than having to proceed sequentially from a starting place.
Dynamic random-access memory (DRAM) - IBM
His brainstorm planted the seed for the invention of dynamic random-access memory, or DRAM, the semiconductor-based memory architecture used by the majority of today’s computers, servers and consumer electronics, including mobile phones, game consoles and digital cameras.
Die-stacked DRAM (3D-DRAM) • Die-stacked DRAM: • Top layers store data • Bottom logic layer stores the various control, access, and interface circuits • Magic: Stacked means high density, so high b/w interposer integration not so expensive. • Current Products: • Hybrid Memory Cube (Micron) • High Bandwidth Memory (Samsung, AMD ...
