Dynamic random-access memory
Videos
Dynamic random-access memory is a type of random-access semiconductor memory that stores each bit of data in a memory cell. A DRAM memory cell usually consists of a microscopic capacitor and a transis

…consequences for some U.S. firms. On 4 December 1985 the US Commerce Department's International Trade Administration ruled in favor of the complaint. Synchronous dynamic random-access memory (SDRAM) was developed by Samsung. The first commercial SDRAM chip was the Samsung KM48SL2000, which had a capacity of 16 Mbit, and was introduced in…
