资料介绍

该文设计了一种OTP存储控制器电路,通过操作OTP存储器指令产生对应不同操作的接口时序,完成对OTP存储器的编程、读取、唤醒、复位、睡眠等操作。同时,在对OTP存储器编程操作中,针对OTP编程易出错的问题,设计了一种编程算法,即对OTP编程地址进行冗余处理,并在编程操作中对同一个地址多次施加脉冲电压,使编程至OTP存储器的数据的正确性急剧提高。嵌入编程算法电路实现了高可靠性的编程算法,有效地控制了OTP存储器的编程操作。因此,该设计的高可靠性OTP存储控制器解决了访问存储器时容易出现编程错误的问题,提高了访问OTP存储器的可靠性。

In this paper,an one time programmable (OTP) memory controller circuit is designed.By operating the OTP memory instruction,the interface timings corresponding to different operations are generated to complete operations such as programming,reading,waking up,resetting,and sleeping on the OTP memory.At the same time,in the OTP memory programming operation,a programming algorithm is designed for the OTP programming error-prone problem.That is,the OTP programming address is redundantly processed,and the pulse voltage is applied to the same address multiple times during the programming operation.The accuracy of data programmed into the OTP memory is dramatically increased.The embedded programming algorithm circuit implements a highly reliable programming algorithm and effectively controls the programming operation of the OTP memory.Therefore,it solved the problem of programming error when accessing memory,and greatly improved the reliability of the OTP memory.
