摘要： A liquid discharge head includes: a nozzle plate including a nozzle; a liquid chamber substrate having an individual chamber; a diaphragm; a piezoelectric actuator including a piezoelectric body, a wiring portion covering a first region of the piezoelectric actuator; and a protective film covering a second region of the piezoelectric actuator other than the first region. A first outer periphery of the piezoelectric body in the second region is interior of a second outer periphery of the individual chamber in the second region. A gap region between the first outer periphery and the second outer periphery has: a first gap region having a first width in the longitudinal direction; and a second gap region having a second width in a transverse direction orthogonal to the longitudinal direction, the second width larger than the first width. The protective film covers a part of the first gap region in the second region.

摘要： Included are a memory cell, a first metal interconnection, a variable capacitance circuit and a connection switch. The memory cell includes cross-coupled first and second inverters which are connected to a power supply node. The first metal interconnection is connected to the power supply node. The variable capacitance circuit includes: second and third metal interconnections electrically connected to a connection node; and a controller capable of controlling electrical connection between the third metal interconnection and the connection node. The connection switch is connected between the first metal interconnection and the connection node of the variable capacitance circuit. The connection switch is configured to electrically connect the first metal interconnection and the connection node in a write operation of the memory cell.
