The data illustrates the quarterly share of the global dynamic random-access memory (DRAM) market held by the leading manufacturers, from 2010 to 2018. In the first quarter of 2018, Samsung held a market share of 44.9%. DRAM, unlike flash memory, is volatile, meaning that information is lost when power is lost. Compared to other volatile memory, such as SRAM, DRAM offers a low-cost, high-capacity solution, which is why it is commonly used as the main memory in modern computing devices and graphics cards. DRAM also possesses a relatively simple structure, allowing it to reach very high densities.
