Automatic repair method for integrated memory circuit using repair position data and fuses of integrated memory circuit, involves programming identified fuses using generated repair position data to repair integrated memory circuit

摘要

The method involves assigning an identifier to each fuse of an integrated memory circuit based on a provided net list, and assigning address information to a group of fuses. Position data of the fuses are determined from a layout, generated based on the net list, to determine if the position data are in conjunction with the net list based on the fuse identifiers. Repair position data are produced from the obtained position data of the fuses and repair data from a tester mechanism. The fuses are then programmed using the repair position data to repair the integrated memory circuit. The net list describes the interconnected electronic components and fuses included in the integrated memory circuit. The address information indicates to which redundant storage areas the fuses are designated or assigned. Allocation between the address information and position data of the fuses is determined based on the conjunction relationship of the position data and address information with respect to the net list. The repair position indicates the position of the fuse that can be programmed for repair.
