| Abstract: | It is very important to study the theory of memory and master the design technology of memory in IC domain. In the paper,we study the theory about EEPROM and master the design technology and fabrication technology of EEPROM. We pay attentions to the key modules’ design technology,such as SDP(Software Data Protection),HD(PHardware Data Protection),page write and so on. The SDP system is used to prevent inadvert-ent writes. A 64kB EEPROM is designed out. The special structure has been implemented on this 64kB EEPROM,which is used to assure its high performance and manufacture. By the diagnosis to internal errors,the endurance is increased. All these research jobs are useful for studying the same kind of memory in the following days. |
