<p><P>PROBLEM TO BE SOLVED: To provide a semiconductor memory device capable of confirming an internal voltage level by utilizing a ready/busy pin. <P>SOLUTION: This semiconductor memory device includes a voltage level detection part, a ready/busy driver controller and a ready/busy driver. The voltage level detection part detects whether the internal voltage is at a fixed voltage level and generates a power-up signal, and the ready/busy driver controller generates a busy enable signal in response to the power-up signal. The ready/busy driver shows that the semiconductor memory device is busy in response to the busy enable signal by the ready/busy pin. <P>COPYRIGHT: (C)2004,JPO</p> |
