Abstract:
A method of creating a non-volatile storage storing a desired data value, said desired data value containing a plurality of bit values at a corresponding plurality of bit positions, said desired data value containing a first count number of a first logical value and a second count number of second logical value, said method comprising:providing a plurality of fuse circuits generating a corresponding plurality of outputs, wherein each of said plurality of fuse circuits is associated with a corresponding one of said plurality of bit positions; blowing a set of fuse circuits at bit positions having values equaling the logical value with a smaller value of said first count number and said second count number, wherein said set of fuse circuits are contained in said plurality of fuse circuits; and inverting all of said outputs if said set of fuse circuits are designed to generate the logical value with a larger value of said first count number and said second count number after being blown.
