DRAMarrays

DRAM arrays refer to the physical arrangement of Dynamic Random-Access Memory (DRAM) cells on a semiconductor chip. These arrays are the fundamental building blocks of DRAM modules, which are commonly used as the main system memory in computers and other electronic devices. Each DRAM cell consists of a single transistor and a single capacitor. The capacitor stores the data bit as an electrical charge, and the transistor acts as a switch to control access to the capacitor for reading or writing data. Due to the nature of capacitors, they leak charge over time, requiring constant refreshing of their contents, hence the term "dynamic."

The DRAM array is organized in a grid-like structure of rows and columns. A unique row address and column address are used to select a specific memory cell for access. The density of DRAM is achieved by packing a vast number of these cells closely together. Manufacturers strive to increase the density of these arrays to fit more memory into the same physical space, leading to higher capacity DRAM modules. The efficiency of the array layout and the interconnects between cells and the memory controller are critical factors in determining the overall performance and speed of the DRAM.
