Abstract: A semiconductor device includes first well regions in a substrate and spaced apart from each other, a connection doped region between the first well regions, and a first interconnection line electrically connected to the connection doped region through a first contact. The first well regions and the connection doped region include impurities of a first conductivity type, and a concentration of the impurities in the connection doped region is higher than that in the first well regions. The first well regions extend into the substrate to a depth larger than that of the connection doped region. A first portion of the connection doped region is disposed in the first well regions and a second portion of the connection doped region contacts the substrate.

Abstract: A memory system includes a memory module that includes a first memory device through a fourth memory device and a first error correction code (ECC) device, and a memory controller that exchanges first user data with each of the first memory device through the fourth memory device through 8 data lines and exchanges first ECC data with the first ECC device through 4 data lines. The memory controller includes an ECC engine that corrects a 32-random bit error of the first user data, based on the first ECC data.
