Implementing eFuse visual security of stored data using EDRAM

A method for implementing Electronic Fuse (eFuse) visual security of stored data using embedded dynamic random access memory (EDRAM), said method comprising:

• providing an EDRAM;
• providing an eFuse having an initial state of a logical 0;
• said EDRAM and said eFuse having a same bit count;
• and
• providing an exclusive OR (XOR) gate receiving respective outputs of said eFuse and said EDRAM, said XOR gate providing an output data combination enabling EDRAM random data to be known at wafer test;
• and enabling said eFuse to be programmed to provide any logical value out of the output data combination, generating a control signal indicating EDRAM data ready for being read with filtering by said eFuse via said XOR gate.
