Abstract
Systems and methods for repairing a memory. A method includes performing a repair analysis of the embedded memories to produce repair information. The method includes storing the repair information in the registers, where the registers are organized into groups having chains of identical length. The method includes performing collision detection between the repair information in each of the groups. The method includes merging the repair information in each of the groups. The method includes repairing the embedded memories using the merged repair information.
Claims20
A method comprising:
- performing a repair analysis of the embedded memories to produce repair information;
- storing the repair information in multiple register chains, each register chain including a plurality of registers, wherein the register chains are organized into groups comprising chains of identical length;
- for each of the groups of the register chains, performing collision detection between the repair information stored in the register chains;
- merging the repair information stored in the register chains when the collision detection indicates no collision between the repair information stored in the different register chains in each of the groups;
- and
- repairing the embedded memories using the merged repair information.

An apparatus, comprising:
- a controller;
- and
- a plurality of embedded memories connected to be accessed by the controller and coupled to register chains, each including a plurality of registers capable of storing repair information, the apparatus configured to:
- perform a repair analysis of the embedded memories to produce repair information;
- store the repair information in the register chains, wherein the register chains are organized into groups comprising chains of identical length;
- for each of the groups of the register chains, perform collision detection between the repair information stored in the register chains;
- merge the repair information stored in the register chains when the collision detection indicates no collision between the repair information stored in the different register chains in each of the groups;
- and
- repair the embedded memories using the merged repair information.
