ABSTRACT:
A semiconductor device performs read or write when read or write command with auto-precharge function is input. The semiconductor device does not carry out the auto-precharge operation until a predetermined auto-precharge delay time passes. Therefore, page mode can be performed while using read or write command with auto-precharge function.
