摘　　要：本文给出了一个有特殊读写方式的１ＭＢＥＰＲＯＭ的结构和关键部分的逻辑设计。采用一脚多用及混用技法，尤其是利用三个输出端兼作高位地址输入端，并加入适当时序设计，能有效地实现１ＭＢＥＰＲＯＭ的自加密。按标准封装管脚给出的地址端进行正常读写，只能读写２５６ＫＢ容量。In this paper architecture of 1MB EPROM with special reading and writing method and key logic design is given. Self-encryption of 1MB EPROM can be realized effectively through using techniques of one dip with MuIti-functions and function ex-changing between two dips,specially using three output terminals for high bit address input terminals and appropriate time-sequence design. Only 256k bits memory space can be read out and written in according to standard dips normally reading and writing for 1MB EPROM made.
