Abstract
PURPOSE:To get rid of a readout error of a data, which is caused by a variation of supplying voltage due to driving a speaker, by inhibiting an alarm output while a dynamic ROM is being read out. CONSTITUTION:While a data of a dynamic ROM is being read out, an output of an alarm signal outputting circuit 30 comes to be unable to pass through an AND gate 31 by a speaker output inhibiting signal 32, and operation of a speaker circuit 2 is inhibited.
