A memory with disabling circuit includes a memory matrix and a disabling circuit. The memory matrix includes a data input/output end and an output enable end. The disabling circuit includes a fuse and an output end. When the fuse is not blown, the disabling circuit transmits the signal of the data input/output end to the output end according to the signal of the output enable end. When the fuse is blown, the disabling circuit generates a tri-state to the output end. Therefore, external circuits cannot perform actions of reading or writing to access the memory matrix.
