- 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 two components—a transistor and a capacitor—DRAM can be made in high densities, and it is inexpensive compared to other types of memory.

How does DRAM work? Memory is made of bits of data or program code that are arranged in a two-dimensional grid. DRAM will store bits of data in what's called a storage or memory cell, consisting of a capacitor and a transistor.

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...
DRAM circuitry is usually organized to have wide rows, i.e., multiple consecutive locations are read in a single access. This particular block of locations is selected by the DRAM row address. Then the DRAM column address is used to select a particular location from the block to be returned.
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.
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, and Hynix) Tradeoffs:
Nov 29, 2023 · RAM has two prevalent forms: dynamic random access memory (DRAM) and static random access memory (SRAM). DRAM : This form requires continuous power and periodic refreshing to retain data. Gaming consoles and computer networking devices utilize DRAM.
