ABSTRACT:
In a semiconductor memory device capable of nibble mode operation, the time period required from the time when CAS signal falls to the time when a data output buffer activating signal rises is made different at the time of a normal mode and at the time of a nibble mode, so that the time period required for reading out data in the nibble mode is reduced as compared with a conventional device.
