Abstract: Disclosed is a method of operating a storage controller, the storage controller communicating with a host and a non-volatile memory device. The method includes receiving a first erase request from the host, the first erase request being for a first zone of a plurality of zones of the non-volatile memory device, loading first allocation list information of the first zone from an allocation list table based on the first erase request, deallocating memory blocks allocated to the first zone based on the first allocation list information, wherein sequential physical page numbers of the memory blocks are respectively mapped onto sequential logical page numbers, and providing the non-volatile memory device with a physical erase request for the deallocated memory blocks of the first zone.

Abstract: A communication device configured to transmit/receive a radio frequency (RF) signal is provided. The device includes a transceiver including an amplifier device using a multi-loop inter-stage matching (ISM) transformer, and a processor configured to control an operation of the amplifier based on a signal strength during transmission/reception of the RF signal. The transformer is disposed between a first amplifier and a second amplifier and includes a plurality of primary loops and a plurality of secondary loops, each primary loop includes an inductor component having a different size and a different Q-factor and each secondary loop includes an inductor component having a different size and a different Q-factor. The processor adjusts an attenuation level of the transformer by controlling a switching connection to the first amplifier and the second amplifier for one primary loop among the plurality of primary loops and one secondary loop among the plurality of secondary loops.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system or a 6th-Generation (6G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system. A frequency multiplier of a wireless communication system is provided. The frequency multiplier includes an input circuit to which a local oscillator (LO) signal is input, a multiplier circuit having one end connected to the input circuit and another end connected to a lower terminal of a load circuit, a load circuit having an upper terminal connected to a voltage controller, and a voltage controller configured between the upper terminal of the load circuit and an input power source, wherein the voltage controller may be configured to drop a voltage between the input power source and the upper terminal of the load circuit and reinput a feedback voltage based on an upper terminal voltage of the load circuit to the voltage controller, and a method of multiplying a frequency using the same.
