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. 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 ...

A schematic drawing depicting the cross-section of the original one-transistor, one-capacitor NMOS DRAM cell. It was patented in 1968. The cryptanalytic machine code-named "Aquarius" used at Bletchley Park during World War II incorporated a hard-wired dynamic memory. Paper tape was read and the characters on it "were remembered in a dynamic ...

Memory is fundamental in the operation of a computer. When combined with a CPU, the ability to run sets of instructions (programs) and store working data becomes possible. Random-access memory (RAM) is a well-known type of memory and is so-called because of its ability to access any location in memory with roughly the same time delay. Dynamic rando...
Invented by Robert Dennard in 1966 at IBM, DRAM works much differently than other types of memory. The fundamental storage cell within DRAM is composed of two elements: a transistor and a capacitor. When a bit needs to be put in memory, the transistor is used to charge or discharge the capacitor. A charged capacitor represents a logic high, or '1',...
DRAM can come in different forms depending on the application. Figure 2 shows a DIMM (dual inline memory module) that contains multiple onboard DRAM chips. This DIMM contains 1 GB of memory, but notice the “2Rx8” printed on the sticker. The 2R means that this module is of rank 2, while the x8 (pronounced “by eight”) denotes the output width of the ...
In this article, we examined the basic principle of operation behind dynamic random access memory, or DRAM. DRAM is extremely common in personal computers and is a basic component that any computer needs to work properly. DRAM works by using the presence or absence of charge on a capacitor to store data. Since a single DRAM cell is composed of only...
Apr 2, 2021 · All RAM types, including DRAM, are a volatile memory that stores bits of data in transistors. This memory is located closer to your processor, too, so your computer can easily and quickly access it for all the processes you do. As you use your computer, it needs to recall data and programming code for the CPU to process.
Definition. Dynamic random-access memory (DRAM) is a type of volatile memory that stores each bit of data in a separate capacitor within an integrated circuit. It is crucial for providing the main memory in computers and other devices, allowing for quick access to data while being less expensive and denser than other types of memory.
May 21, 2023 · To start with, DRAM is also known as Dynamic Random-Access Memory or Dynamic RAM. Furthermore, it is a type of computer memory (RAM) widely used in modern electronic devices. It is a volatile memory technology that stores data temporarily while the computer is powered on. This allows the computer’s processor to quickly access needed data in ...

Apr 25, 2024 · Dynamic Random Access Memory (DRAM) was first developed in the early 1960s, in response to the need for more efficient and cost-effective memory solutions in computing. The invention of DRAM is often credited to Dr. Robert Dennard of IBM, who patented the technology in 1968. His design simplified the memory cell structure to a single transistor ...
