Abstract

A magnetic random access memory (MRAM) having a vertical structure transistor has the characteristics of faster access time than SRAM, high density as with DRAM, and non-volatility like a flash memory device. The MRAM has a vertical structure transistor, a first word line including the transistor, a contact line connected to the transistor, a magnetic tunnel junction (MTJ) cell deposited on the contact line, a bit line deposited on the MTJ cell, and a second word line deposited on the bit line at the position of MTJ cell. With the disclosed structure, it is possible to improve the integration density of a semiconductor device, to increase the short channel effect, and to improve the control rate of the resistance, while using a simplified manufacturing process.
