Abstract
A method and circuit for implementing Electronic Fuse (eFuse) visual security of stored data using embedded dynamic random access memory (EDRAM), and a design structure on which the subject circuit resides are provided. The circuit includes EDRAM and eFuse circuity having an initial state of a logical 0. The outputs of the eFuse and an EDRAM are connected through an exclusive OR (XOR) gate, enabling EDRAM random data to be known at wafer test and programming of the eFuse to provide any desired logical value out of the XORed data combination.
