<p><P>PROBLEM TO BE SOLVED: To provide a semiconductor device that can respond to data writing control from the other system even immediately after power application. <P>SOLUTION: After power application, upon initial writing control from an IF circuit B 132 of the semiconductor device B 131 in a power B system 130 that is an external device, that is, when a signal applied to a writing control line NWR by the IF circuit B 132 rises or falls, the output level of an IF circuit toggle signal generation circuit 122 is inverted to cancel the reset of an IF circuit A 120. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
