摘　　要：针对E2PROM写入寿命有限的缺点,首先提出了分区域遍历轮循的数据动态存储策略,给出了定义E2PROM数据存储协议的方法,详细阐述了这种策略的程序设计思路;接着以一种增量型计数器的设计为例,提出了另一种"写零计数"的E2PROM数据遍历轮循存储策略,阐述了设计思路,通过对比发现,采用这两种存储策略能有效地提高E2PROM写入寿命,且程序设计简单可行。Two methods are put forward in this paper to prolong the life-span of E2 PROM despite of its limit life-span shortcomings. It is an effect way to record the new data one by one in the set E2 PROM unit area circularly. A concerned protocol of data storage and program designing are detailed in this paper, the second dynamic storage technique as ＂writing and counting zeros＂ is interpreted by desig ning an up-forward counter. The effect of this method is emphasized.
