Abstract: An operating method of a storage device, the method including; loading journal data from a non-volatile memory device, identifying a cache allocation flag included in the journal data, and restoring meta data corresponding to the journal data to a storage controller in response to the cache allocation flag. Here, the cache allocation flag is a first flag when the meta data are allocated to a meta cache of the storage controller, and the cache allocation flag is a second flag when the meta data are stored to a meta buffer of the storage controller.

Abstract: A test device includes a main board. First and second device under test (DUT) boards are disposed on the main board. First and second semiconductor devices are mounted on the first and second DUT boards, respectively. The first and second semiconductor devices are DUTs. First and second connectors are respectively disposed at a first end and a second end of the first DUT board. The first and second connectors are spaced apart from each other and respectively transmit first and second signals. The first signal forms a first electrical path along which the first signal is input to the first DUT board via the first connector. The second signal forms a second electrical path along which the second signal is output from the first DUT board and input to the second DUT board via the second connector.

Abstract: A storage device is provided which includes an ECC circuit. At a write operation, the ECC circuit generates a CRC (cyclic redundancy check) parity corresponding to data and generates an ECC (error correction code) parity corresponding to the data using an error correction code. At a read operation about the data stored in the at least one nonvolatile memory device, the ECC circuit corrects an error of the data using the CRC parity and the ECC parity.

Abstract: Provided are data compression method, data compression apparatus, and memory system. The data compression method includes receiving input data and generating a hash key for the input data, searching a hash table with the generated hash key, and if it is determined that the input data is a hash hit, compressing the input data using the hash table; and searching a cache memory with the input data, and if it is determined that the input data is a cache hit, compressing the input data using the cache memory.
