摘要： A memory element capable of simultaneously satisfying the number of repeating operation times and a low-voltage operation characteristic which are in a tradeoff relation is provided. The memory element has a high-resistivity layer and an ion source layer between a bottom electrode and a top electrode. The high-resistivity layer is made of an oxide containing Te. Any of elements other than Te such as Al, Zr, Ta, Hf, Si, Ge, Ni, Co, Cu, and Au may be added. In the case of adding Al to Te and also adding Cu and Zr, the composition ratio of the high-resistivity layer is preferably adjusted in the ranges of 30≦Te≦100 atomic %, 0≦Al≦70 atomic %, and 0≦Cu+Zr≦36 atomic % except for oxygen. The ion source layer is made of at least one kind of metal elements and at least one kind of chalcogen elements of Te, S, and Se.

摘要： A memory element and a memory device with improved controllability over resistance change by applied voltage are provided. The memory element includes a first electrode, a memory layer, and a second electrode in this order. The memory layer includes a resistance change layer provided on the first electrode side, and an ion source layer provided on the second electrode side and is higher in resistance value than the resistance change layer. A resistance value of the resistance change layer is changeable in response to a composition change by applied voltage to the first and second electrodes

摘要： An information processor equipped with a password storage for storing a password, which is inputted from outside for unlocking a password-locked condition of a storage device when booting the information processor. During a resume process, a controller unlocks the password-locked condition of the storage device using the password previously stored in the password storage. With this arrangement, when the information processor resumes its normal operating condition from a power saving mode, the operator does not need to input a password even if the information processor is installed in an unattended environment or a far remote local area.
