MEMORY REWRITING SYSTEM

摘要: PURPOSE:To prevent performance from being dropped by comparing error generating syndrome with an initial value stored in a memory or the preceding value, and at time of same bit, inhibiting rewriting. CONSTITUTION:The addresses are always applied to 1 4. Simultaneously reading contents 1, 4 also read out set up register 7, when exists data bit display is 6. Independently existence error, both registers 6, 7 compared each other comparator 8 result signal 81 informed rewriting control circuit 10. When continuous based upon not rewritten.
