Abstract
Provided is a storage device including a first antifuse element and a second antifuse element, and a supply line extending from a single power supply is branched into supply lines so that the respective supply lines are connected to the first antifuse element and the second antifuse element. A control circuit causes a voltage application to the first antifuse element and a voltage application to the second antifuse element to be alternately performed.
Claims20
A storage device comprising:
- a first antifuse element and a second antifuse element, the storage device being configured such that a supply line extending from a single power supply is branched into supply lines so that the respective supply lines are connected to the first antifuse element and the second antifuse element;
- and
- a control circuit configured to cause a first voltage application to the first antifuse element and a second voltage application to the second antifuse element to be alternately performed.
A printing head comprising an element substrate in which a printing element for discharging liquid is formed,
- wherein the element substrate includes a storage device,
- wherein the storage device includes:
- a first antifuse element and a second antifuse element, the storage device being configured such that a supply line extending from a single power supply is branched into supply lines so that the respective supply lines are connected to the first antifuse element and the second antifuse element;
- and
- a control circuit configured to cause a first voltage application to the first antifuse element and a second voltage application to the second antifuse element to be alternately performed.
A method for a storage device including a plurality of first antifuse elements and a plurality of second antifuse elements, the storage device being configured such that a supply line extending from a single power supply is branched into supply lines so that the respective supply lines are connected to the plurality of first antifuse elements and the plurality of second antifuse elements, the method comprising:
- selecting a pair of a first antifuse element and a second antifuse element corresponding to two bits from among the plurality of first antifuse elements and the plurality of second antifuse elements;
- and
- alternately performing voltage applications to the pair of the first antifuse element and the second antifuse element.
