Apparatuses and methods for switching refresh state in a memory circuit

Abstract:

An apparatus may include a semiconductor device that includes an internal clock circuit configured to receive an internal clock signal and to provide a local clock signal based on the internal clock signal. The internal clock circuit comprises a clock synchronizer configured to, in response to receipt of a command to exit a self-refresh mode, disable provision of the local clock signal by a number of cycles of the internal clock signal.
