Abstract (en)

[origin: WO2021239911A1] The invention relates to a device for implementing one or more logical operations according to one embodiment. Each of the one or more logical operations has one or more binary input variables and has a binary output value dependent on the logical operation executed and dependent on the one or more binary input variables. The device comprises one or more switchable elements (111, 112). The device is configured to execute write operations and read operations. More specifically, the device is configured to execute each of the write operations in such a manner that a write bias is applied to one of the one or more switchable elements (111, 112), which write bias switches the switchable element into a first state or into a second state dependent on the write bias, the second state being different from the first state. The device is further configured to execute each of the read operations in such a manner that a read bias is applied to one of the one or more switchable elements (111, 112), to determine whether the switchable element has been switched to a first state or to the second state. The device is configured to select, for each of the one or more binary input variables of each of the one or more binary operations, the write bias of at least one of the write operations dependent on said binary input variables. The device is further configured to determine the binary output value of each of the one or more logical operations by applying the read voltage of one of the read operations dependent on the state in which one of the one or more switchable elements (111, 112), to which the read voltage is applied, has been switched.
