Abstract

PURPOSE: To use efficiently a device by varying the read accuracy by a read block.
CONSTITUTION: The maximum resemblance Rmax is stored in the register 1, the reference value T1 and T2 (T1>T2) are set to the registers 2, 3, respectively, and the flag F is set to the FF4. When the flag F on the FF4 is on, the reference T1 is selected by the gate 5, and when the flag F is off, the gate 6 is opened, the reference value T2 is selected, and both of them are input to the comparator 7 and are compared with the maximum resemblance Rmax. And the size of the resemblance Rmax and the reference value Ti (i=1 or 2) is compared, and it is acceptedd in case of Rmax≤Ti, and it is rejected in case of Rmax>Ti. In this way, as for the block which requires the read accuracy, a read error can be removed, and as for the block which requires no read accuracy, it is possible to make the reference value free from rejection even if a read error occurs to some extent, and therefore an efficient read is executed.
