摘要： A method for updating stored information and an apparatus. A controller performs error correction code (ECC) decoding on stored data information based on the stored data information and stored ECC check information to generate an error-corrected codeword, where the error-corrected codeword includes error-corrected data information. The controller generates candidate to-be-written data information based on the error-corrected data information and a data update indication. The controller performs a mask operation on the candidate to-be-written data information based on the stored data information, and writes unmasked content in the candidate to-be-written data information into a memory.

摘要： The present invention discloses a mode multiplexer/demultiplexer and a switching node. The mode multiplexer/demultiplexer includes a multi-mode optical waveguide, a first transmission optical waveguide, and a second transmission optical waveguide. The multi-mode optical waveguide includes a first mode channel and a second mode channel. The first transmission optical waveguide includes a first coupling region that includes a first fundamental-mode channel, and the first fundamental-mode channel performs optical mode coupling with the first mode channel in the multi-mode optical waveguide. The second transmission optical waveguide includes a second coupling region that includes a second fundamental-mode channel, and the second fundamental-mode channel performs optical mode coupling with the second mode channel in the multi-mode optical waveguide. An effective refractive index of a fundamental-mode optical signal in the first coupling region is different from an effective refractive index of the same fundamental-mode optical signal in the second coupling region.
