Abstract
PURPOSE: To recover the error due to peak shift in readout data, by developing several kinds of clock pulses different in the phase as clock pulses used for fetch of readout data and using these with switching.
CONSTITUTION: When a peak shift is caused and the readout data causes a phase shift from the normal position shown in dotted lines to the position in solid lines, if the readout data is fetched at the trailing of clock pulse, an error such as fetched data 1 as shown in figure is produced. If this error is taken place, after another clock pulse 2 is selected at the selection circuit according to the selection signal given to control signal lines 22, 23, readout is again executed. In this case, the readout data is correctly fetched and a fetched data 2 shown in figure can be obtained. If error is not recovered even with rereadout, further another clock pulse 3 is selected.
