METHOD FOR COUNTING BEYOND ENDURANCE LIMITATIONS OF NON-VOLATILE MEMORIES

摘要

Digit counter (such as, Fig. 1), it is a kind of use nonvolatile memory (12,14,16,18..) as storage unit, wherein storage unit is divided into two groups, one for implementing rotary counter (20,22), only most of count of each tracking counts with binary counter (10), the more live part of the first tracking. That maximization of the rotary counter is realized before count method, therefore in the fatigue limit memory that can be obtained, changed by each state of each cell of determination and be recorded consistent counting and all rotary counters two state changes of experience of that, in each circulation. Binary counter (10) records cycle-index, which, which has, passes through.
