WIPO Patent Application WO/2010/032468
Kind Code:
A1
Abstract:
Disclosed is a storage element provided with a resistance variable element (1) wherein an electrical resistance value of each of the storage elements (3) arranged in matrix in a storage device (21) changes when an electrical pulse having the positive or negative polarity is applied, and the changed electrical resistance value is maintained; and a current suppressing element (2) which suppresses a current that flows when the electrical pulse is applied to the resistance variable element. The current suppressing element is composed of a first conductor layer containing tantalum and a tantalum nitride containing nitrogen, a semiconductor layer containing silicon and a silicon nitride containing nitrogen on the first conductor layer, and a second conductor layer containing tantalum and a tantalum nitride containing nitrogen on the semiconductor layer.
