Abstract: A computing system includes a host and a storage device. The host includes a central processing unit (CPU) and a first volatile memory device. The storage device includes a second volatile memory device and a nonvolatile memory device. The CPU uses the first volatile memory device and the second volatile memory device as a main memory to store temporary data used for operation of the CPU. The CPU determines a swap-out page to be swapped-out of first pages stored in the first volatile memory device, determines a swap-in page to be swapped-in of second pages stored in the second volatile memory device, and exchanges the swapped-out page and the swapped-in page.

Abstract: A test device includes a data driver and a controller. The controller is configured to generate a test code by dividing a test sequence in a unit of n-bits. The data driver is configured to receive the generated test code and output one of input voltages to a device under test as a test signal based on the generated test code. A storage device stores a test sequence.

Abstract: A method of operating a storage device includes receiving a first logical address from a host, determining whether first metadata stored in a volatile memory of the storage device and associated with the first logical address is corrupted, processing the first metadata as an uncorrectable error when the first metadata is determined to be corrupted, providing an error message to the host indicating that an operation cannot be performed on data associated with the first logical address when the first metadata is processed as the uncorrectable error, after the providing of the error message, receiving a second logical address from the host, determining whether second metadata stored in the volatile memory and associated with the second logical address is corrupted, and performing an operation of accessing the non-volatile memory based on the second metadata, when the second metadata is not determined to be corrupted.

Abstract: Disclosed are a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. Disclosed is a method by which a terminal performs a random access, comprising: receiving, from a serving base station, a handover command including configuration information indicating a dedicated random access resource and a common random access resource determining whether to perform a random access by using at least one of the dedicated random access resource and the common random access resource according to predetermined criteria; and performing the random access on the basis of the determination result.
