Title:
積和演算器、ニューロモーフィックデバイスおよび積和演算器の使用方法
Document Type and Number:
Japanese Patent JP6721136
Kind Code:
B2
Abstract:
A multiply and accumulate calculation device (1) includes a multiple calculation unit (10) and a accumulate calculation unit (11). The multiple calculation unit (10) includes a plurality of multiple calculation elements (10AA, 10AB), which are variable resistance elements, and at least one reference element (10AMAX, 10AMIN). The accumulate calculation unit (11) includes an output detector (11A) configured to detect a total value of at least outputs from the plurality of multiple calculation elements. Each of the plurality of multiple calculation elements is a magnetoresistance effect element including a magnetized free layer having a magnetic domain wall, a magnetization fixed layer in which a magnetization direction is fixed, and a nonmagnetic layer sandwiched between the magnetized free layer and the magnetized fixed layer. The reference element is a reference magnetoresistance effect element having a magnetization free layer that does not have the magnetic domain wall.
