<p>PURPOSE: To shorten the precharging time of the memory element and increase the processing speed of data by interrupting precharging when the precharging is completed. CONSTITUTION: While a data line is precharged, a precharging circuit 10 is precharged as well as the precharging state of the data line, and a sense circuit 20 senses the state wherein the precharging is performed by the precharging circuit 10. After the signal from the sense circuit 20 is temporarily stored in a storage circuit 30, it is applied to a sensor amplifier 2 and the output of a clock signal for precharging the input side of the amplifier 2 is controlled. Namely, when the sense circuit 20 senses the completion of the precharging by the precharging circuit 10, the precharging of the data line is stopped and data stored in a dummy cell 1' is outputted according to an address inputted through address lines A0-A7.</p> |
