摘要： A method includes reading data from a subset of a plurality of memory bit cells of a non-volatile memory. The data identifies an address of at least one individual failed bit cell. The method further includes loading the data directly into a register, receiving an address of data to be accessed, determining if the received address is the address of any individual failed bit cell; and accessing the data of the register if the received address is the address of any individual failed bit cell.

摘要： A sense amplifier for detecting a logic state of a selected electrical fuse cell among a number of unselected electrical fuse cells includes a bias module coupled to a power supply for generating a first current, and a tracking module coupled to the bias module for generating a second current. A current supplier is coupled to the bias module and the tracking module for generating a third current substantially equal to a sum of the first and second currents scaled by a predetermined factor, the third current being diverted into a first sub-current flowing through the selected electrical fuse cell and a second sub-current leaking through the unselected electrical fuse cells. The tracking module is so configured that the second current scaled by the predetermined factor is substantially equal to the second sub-current, thereby avoiding the first sub-current to be reduced by the second sub-current.
