Abstract

PURPOSE: To avoid occurrence of the erroneous stop signal by stopping application of new writing pulse to the memory when the reading output becomes larger than the tuning voltage delivered from the analog voltage generator circuit.
CONSTITUTION: The reading output given from memory MA1 of data memory 107 is converted into the tuning voltage through converter circuit 110, and then turned to the tuning voltage through polarity inversion and amplification at inverse amplifier 50. Comparator 111 delivers the stop signal when the output of amplifier 50 becomes larger than the output of tuning voltage generator 102. In such constitution, no output of mode memory MA1 exists in the erasion mode or the writing mode, and accordingly no stop signal is caused even though the output of amplifier 50 is 0. In short, the stop signal is produced only in the reading mode
