SEMICONDUCTOR DEVICES

摘要

The semiconductor device includes a pre-internal refresh signal generator and an internal refresh signal generator. The pre-internal refresh signal generator receives a first periodic signal during a refresh operation to generate a pre-internal refresh signal including pulses which are periodically created. The internal refresh signal generator receives a second periodic signal during the refresh operation to generate first and second internal refresh signals sequentially enabled by the pulses of the pre-internal refresh signal.

1. A semiconductor device comprising:
a pre-internal refresh signal generator suitable for receiving a first periodic signal in response to a refresh termination command signal during a refresh operation to generate a pre-internal refresh signal including pulses which are periodically created; and an internal refresh signal generator suitable for receiving a second periodic signal during the refresh operation to generate first and second internal refresh signals sequentially enabled by the pulses of the pre-internal refresh signal.
