Abstract
An electronic device includes a command generation circuit configured to generate a refresh command and a driving control signal, which are enabled during an all-bank refresh operation, according to a logic level combination of an internal chip selection signal and an internal command address. The electronic device also includes a buffer control circuit configured to generate, from the refresh command and the driving control signal, a first buffer enable signal for enabling a first group of buffers and a second buffer enable signal for enabling a second group of buffers.

An electronic device comprising:
- a command generation circuit configured to generate a refresh command and a driving control signal, which are enabled during an all-bank refresh operation, according to a logic level combination of an internal chip selection signal and an internal command address;
- and
- a buffer control circuit configured to generate, from the refresh command and the driving control signal, a first buffer enable signal for enabling a first group of buffers and a second buffer enable signal for enabling a second group of buffers.
An electronic device comprising:
- a command generation circuit configured to generate a refresh command and a driving control signal, which are enabled during an all-bank refresh operation, according to a logic level combination of an internal chip selection signal, a first group of internal command addresses, and a second group of internal command addresses, and configured to generate an internal command by detecting a logic level combination of the internal chip selection signal and the second group of internal command addresses during the all-bank refresh operation;
- and
- a buffer control circuit configured to generate, from the refresh command and the driving control signal, a first buffer enable signal for enabling a first group of buffers and a second buffer enable signal for enabling a second group of buffers.
