Abstract: A capacitor includes a first electrode and a second electrode spaced apart from each other, a dielectric layer disposed between the first electrode and the second electrode, and a seed layer disposed between the first electrode and the dielectric layer. The dielectric layer includes a dielectric material having a tetragonal crystal structure. The seed layer includes a seed material that satisfies at least one of a lattice constant condition or a bond length condition.

Abstract: Disclosed is a method of operating a storage controller which communicates with a host and a non-volatile memory device. The method includes receiving a first state transition request for a device open from the host, performing a first active zone refresh operation of the non-volatile memory device in response to the first state transition request such that a zone, which has an active state before an immediately previous power-off is processed to a sequentially writable state in one block, receiving, by a first buffer memory, first target data to be stored in a first block of a first zone among the plurality of zones from the host depending on a first write request, receiving a first power-off request from the host, during processing the first write request, and storing the first target data in a first power loss protection (PLP) block of the non-volatile memory device.
