Abstract
A semiconductor device that includes macro cells and a fuse of smaller size. Each macro cell includes normal blocks and a redundant block. Each normal block includes circuits each having a predetermined function. The redundant block has the same function as the normal blocks have. If one of the normal blocks does not work well, it will be replaced with the redundant block. The fuse holds information for specifying the normal block to be replaced with the redundant block included in the macro cell. This fuse is shared by a plurality of macro cells.
Claims8
A semiconductor device comprising:
- a plurality of macro cells each including a plurality of normal blocks each including circuits each having a predetermined function and a redundant block having the same function as the normal blocks have and used, in the case of one of the normal blocks not working well, in place of the normal block and;
- a fuse for holding information for specifying the normal block to be replaced with the redundant block included in the macro cell,
- wherein the fuse is shared by the plurality of macro cells.
