<p>PURPOSE:To greatly improve operation convenience of a system when a device is incorporated in the system. CONSTITUTION:An internal address counter circuit 200 which uses an inverted signal of a detecting pulse for ON operation of a power supply as a reset signal is provided. When the power supply is turned on, output of the internal address counter circuit 200, that is, output of all the load counters CNT1-CNTn which compose the internal address counter circuit 200 are reset to '0'. Based on this state, the internal address counter 200 starts to count up every time recall operation of a memory cell in a memory array is repeated. When a state of output addresses of all the load counters CNT1-CNTn becomes '1', output phi8 of an AND circuit 280 which is connected to the internal address counter circuit 200 is changed from '0' to '1', a latch-reset signal phi8 which reports the reset state of recall operation to the pulse generation circuit is outputted, and the recall state is reset.</p> |
