EMBEDDED ELECTRICALLY PROGRAMMABLE READ ONLY MEMORY DEVICES

摘要

The present invention teaches novel electrically programmable read only memory (EPROM) devices (411) for embedded applications. EPROM devices (411) of the present invention utilize existing circuit elements without complicating existing manufacture technologies. They can be manufactured by dynamic random access memory (DRAM) (401) technologies, standard logic technologies, or any type of devices do not require high voltage circuits to support their programming operation. EPROM devices (411) of the present invention are ideal for embedded applications. Typical applications including the redundancy circuits for DRAM, the programmable firmware for logic products, and the security identification circuits for IC products.
