Abstract
A memory device includes a first strobe delay circuit delaying a first data strobe signal to generate a delayed first data strobe signal, a first write leveling circuit sampling a first delay clock in synchronization with the delayed first data strobe signal, a second strobe delay circuit delaying a second data strobe signal to generate a delayed second data strobe signal, a replica second strobe delay circuit delaying the first data strobe signal by a delay value obtained by replicating the second strobe delay circuit to generate a replica delayed second data strobe signal; and a second write leveling circuit sampling a second delay clock in synchronization with the delayed second data strobe signal in a first I/O mode, and sampling the second delay clock in synchronization with the replica delayed second data strobe signal in a second I/O mode.
