Title:
情報処理装置および情報処理装置の駆動方法
Document Type and Number:
Japanese Patent JP7398841
Kind Code:
B2
Abstract:
This brain-type information processing device has an analog resistance changing element composed of a pair of electrodes and an oxide layer provided between the pair of electrodes, and a drive circuit that superimposes and supplies voltage fluctuations that have fluctuation components on/to drive signals of the analog resistance changing element. By superimposing voltage fluctuations that cause current fluctuations in the drive signals, it is possible to minimize irregular resistance changes in a resistance-lowering (SET) process and in a resistance-raising (RESET) process during the driving of the analog resistance changing element. Due to the minimizing of the irregular resistance change characteristic, noise of the resistance change component can be removed, the resistance change becomes smooth, the power consumption of the brain-type information processing device can be reduced, and the speed of the device can be increased.
