PURPOSE: Handling of recording operations within a memory device accurately tracks the timing of the recording operations within a memory by forming a recording self-timed path. CONSTITUTION: A control circuit (30) controls a signal supplied to a word line and a bit line of an array and controls a recording operation and a reading operation. A dummy column (35) includes multiple dummy memory cells (40) for a load and dummy memory cells (50) for record timing. A dummy record driver circuit (60) is connected to a dummy bit line. A record detection circuit (65) generates a recording termination signal to the control circuit to terminate the recording operation when a state flip condition is generated.
