In a method of an MRAM device, first and second patterns are formed on a substrate alternately and repeatedly in a second direction. Each first pattern and each second pattern extend in a first direction perpendicular to the second direction. Some of the second patterns are removed to form first openings extending in the first direction. Source lines filling the first openings are formed. A mask is formed on the first and second patterns and the source lines. The mask includes second openings in the first direction, each of which extends in the second direction. Portions of the second patterns exposed by the second openings are removed to form third openings. Third patterns filling the third openings are formed. The second patterns surrounded by the first and third patterns are removed to form fourth openings. Contact plugs filling the fourth openings are formed.

Disclosed is a novel use of rice, rice bran or rice hull extract as a histamine receptor antagonist. The rice, rice bran or rice hull extract may be used as a natural antihistamine to prevent or treat allergic rhinitis, inflammatory bowel disease, asthma, bronchitis, nausea, gastric and duodenal ulcer, gastroesophageal reflux disease, sleep disorder, anxiety and depression. It provides comparable or better effect of decreasing sleep latency, increasing sleep duration and increasing non-REM sleep as compared to diazepam, which is currently used as sleeping drug. Derived from the natural product rice, rice bran or rice hull, it has no side effect such as cognitive impairment, resistance or dependency even after long-term use.
