The present disclosure provides a content addressable memory (CAM) for repairing firmware of multi-plane read operations in a flash memory device. The CAM comprises a set of CAM registers configured to store a mapping table. The mapping table comprises a plurality of old addresses, each old address corresponding to a new address. The CAM also comprises N comparators coupling to the set of CAM registers, and configured to compare the old addresses with N input signals for performing the multi-plane read operations on N memory planes, wherein N is an integer greater than 1. The CAM further comprises N multiplexers coupling to the N comparators respectively and to the set of CAM registers, and configured to generate N output signals for the multi-plane read operations. At least one of the N output signals comprises the new address according to the mapping table and a comparison output by the comparators.
