Apparatus and method of analyzing magnetic random access memory

摘要

An analysis apparatus of MRAM and analysis method thereof are provided. The analysis apparatus includes: an MRAM mounting unit on which an MRAM is mounted; a magnetic-field applying unit which is positioned around the MRAM mounting unit and applies an external magnetic field to the MRAM mounted on the MRAM mounting unit; a probe card which is located in a position corresponding to the MRAM mounting unit; a matrix switch unit which designates a unit cell of the MRAM; a source measurement unit which applies an internal magnetic field to the unit cell of the MRAM or measures a resistance of the unit cell of the MRAM; and a computer unit which stores and analyzes data regarding the measured resistance of the each unit cell of the MRAM. The analysis apparatus and method can analyze characteristics of the unit cells with a relatively simple structure and at a fast speed.
