动态随机存取存储器（Dynamic Random Access Memory，DRAM）是一种半导体存储器，主要的作用原理是利用电容内存储电荷的多寡来代表一个二进制比特（bit）是1还是0。由于在现实中晶体管会有漏电电流的现象，导致电容上所存储的电荷数量并不足以正确的判别数据，而导致数据毁损。
15 de dic. de 2021 · La DRAM es una forma de RAM y tiene varios tipos dentro de su categoría. La DRAM es volátil, como toda la RAM, por lo que no puede conservar datos sin energía. La DRAM es rápida, y viene en diferentes velocidades y opciones de latencia. Busca un número mayor de velocidad (MHz) y un número menor de latencia (CL) para obtener los mejores ...
2 de abr. de 2021 · DRAM is a form of RAM, and it has several types within its category. DRAM is volatile, like all RAM, so it can’t hold data without power. DRAM is fast and comes in different speeds and latency options. Look for a higher speed (MHz) number and a lower latency (CL) number for the best results.
The dram (alternative British spelling drachm; apothecary symbol ʒ or ℨ; abbreviated dr): C-6–C-7 is a unit of mass in the avoirdupois system, and both a unit of mass and a unit of volume in the apothecaries' system. It was originally both a coin and a weight in ancient Greece. The unit of volume is more correctly called a fluid dram, fluid drachm, fluidram or fluidrachm (abbreviated fl ...
DRAM (dynamic random access memory): Dynamic random access memory (DRAM) is a type of memory that is typically used for data or program code that a computer processor needs to function. DRAM is a common type of random access memory ( RAM ) used in personal computers (PCs), workstations and servers. Random access allows the PC processor to ...
dram 设计所采用的技术十分简单，只需要一个晶体管，而一个典型的静态 ram（sram 存储器单元）大约需要六个。由于设计简洁，因此可以实现极高的集成密度。它可以存储大量的数据，能够在处理的同时自行刷新和删除数据。此外，dram 的成本远远低于 sram，同时 ...
工作原理 [編輯] DRAM讀操作舉例，在簡單的4x4矩陣上. DRAM通常以一個電容和一個電晶體為一個單元排成二維矩陣，左圖所示是一個4×4的矩陣。 基本的操作機制分為讀(Read)和寫(Write)，讀的時候先讓Bitline(BL)先充電到操作電壓的一半，然後再把電晶體打開讓BL和電容產生電荷共享的現象，若內部儲存的值 ...
