The invention provides an error correction device and method of a multichannel flash memory controller and a multichannel flash memory controller. The error correction device comprises a coding/decoding module and an error calculating module, wherein the coding/decoding module specifically comprises a combined logic circuit and a plurality of time sequence logic circuits which correspond to a plurality of channels; the coding/decoding module further comprises a multiple selector for selecting data and time sequence logic register information of a corresponding effective channel into the combined logic circuit according to the data effectiveness of each channel at a current period, and an input module for inputting an operation result of the combined logic circuit into a time sequence logic register of the corresponding effective channel. Due to the adoption of the error correction device, error correction method and multichannel flash memory controller disclosed by the embodiment of the invention, the problems of extremely high cost and waste of a large quantity of resources caused by independent occupation of an error correction module by each channel in an error correction method in the prior art. |
