    摘要: Настоящее изобретение описывает элемент магниторезистивной памяти, состоящий из ячеек магнитной памяти с произвольным доступом (MRAM), содержащих туннельный магнитный переход и имеющих улучшенную эффективность переключения, более низкое потребление электроэнергии, обладающий повышенной устойчивостью к внешним магнитным полям и обеспечивающий достоверность считываемых данных. Технический результат заключается в повышении сохранности информации в элементах на битовых ячейках памяти MRAM. Для осуществления указанного технического результата в предпочтительном варианте осуществления заявлен элемент магниторезистивной памяти (MRAM), состоящий из двух ячеек MRAM, каждая из которых содержит по меньшей мере один слой магнитного материала с изменяемой ориентацией вектора намагниченности (свободный слой) и по меньшей мере один составной слой (опорный слой), состоящий из двух противоположно направленных магнитных слоев с фиксированным направлением вектора намагниченности, направление которого определяется по слою, ближайшему к свободному слою, причем легкие оси ячеек являются сонаправленными, вне зависимости от пространственного расположения ячеек, и намагниченности свободных слоев каждой из ячеек являются противоположено направленными.

    摘要: Embodiments include apparatuses, systems, and methods including a memory apparatus including a plurality of bit cells, wherein each of the plurality of bit cells correspond to a respective weight value and include a switch device that has a magnetic tunnel junction (MTJ) or other suitable resistive memory element to produce stochastic switching. In embodiments, the switch device may produce a switching output according to a stochastic switching probability of the switch device. In embodiments, a bit line or a source line passes a current across the MTJ for a switching time associated with the stochastic switching probability to produce the switching output which enables a determination of whether the respective weight value is to be updated. Other embodiments may also be described and claimed.
