Abstract

PURPOSE: To eliminate meaningless display and arithemtic by rewriting the read memory content of a storage unit beyond a fixed range of BCD codes into specific data within the range.
CONSTITUTION: Full adder 24 detects a data signal read out from storage unit 10, stored with a code signal from input terminal 22 on a four-bit and one-word unit, being beyond a fixed range of BCD codes, and the contents of a group of memory cells strored with the read out signal are rewritten into specific codes belonging to BCD codes under the control of write-read control circuit 18. Simultaneously, the contents of latch circuits 13 and 14 are reset by a carry out signal from full adder 24. Then, the rewritten contents are read out from storage unit 10 again and displayed on display units 1 and 2.
