A memory element includes: an electrical fuse provided to be inserted between a first input node and a second input node; and an antifuse provided to be inserted between the second input node and a third input node. The third input node is configured to be a node to which a voltage is allowed to be applied separately from a voltage to be applied to the first input node.

Memory element, semiconductor device, and writing method

A semiconductor device has an electrical fuse element including: a first filament; a second filament connected to the first filament; and a series readout section connected to an end of the first filament opposite to another end of the first filament connected to the second filament, the series readout section reading series resistance of the first filament and the second filament.

Semiconductor device having an electrical fuse element

An electric fuse includes: a filament having a first conductive layer and a second conductive layer formed on the first conductive layer, wherein at least three discernible resistive states are generated in the filament by changing of a combination of a state of the first conductive layer and a state of the second conductive layer.

Electric fuse, semiconductor device, and information writing method of electric fuse

A nonvolatile storage device includes: a plurality of memory mats each including a plurality of memory cells; a plurality of plate electrodes each provided for every individual one of the memory mats and each used for applying a voltage to the memory cells; a power-supply section configured to apply a voltage to each of the plate electrodes; a switch circuit having a plurality of switches provided between the power-supply section and each of the plate electrodes and between the plate electrodes; and a control section configured to control the switch circuit in order to disconnect the plate electrodes from the power-supply section and to connect the plate electrodes to each other in order to carry out electrical charging and discharging operations among the plate electrodes.
