摘要:
Non-volatile solid-state memory-based storage devices and methods of operating the storage devices to have low initial error rates. The storage devices and methods use bit error rate comparison of duplicate writes to one or more non-volatile memory devices. The data set with a lower bit error rate as determined during verification is maintained, whereas data sets with higher bit error rates are discarded. A threshold of bit error rates can be used to trigger the duplication of data for bit error comparison.

Provided are a storage system for supporting a copy command and a move command and an operation method of said storage system. The storage system performs a copy operation and a move operation without movement of data between a host and a storage device, by using a copy command and a move command which are distinguished from a read command and a write command. More specifically, the storage device updates a mapping table by responding to the reception of the copy command or the move command from the host.
