Abstract
One exemplary storage controller of controlling data access of a storage device includes an encoding circuit and a control circuit. The encoding circuit is programmable to support a plurality of different finite fields, and implemented for generating encoded data according to an adjustable finite field setting. The control circuit is implemented for controlling the adjustable finite field setting of the encoding circuit and recording data into the storage device according to the encoded data. Another exemplary storage controller of controlling data access of a storage device includes a decoding circuit and a control circuit. The decoding circuit is programmable to support a plurality of different finite fields, and implemented for generating decoded data according to an adjustable finite field setting. The control circuit is implemented for reading data from the storage device to obtain readout data and controlling the adjustable finite field setting of the decoding circuit.
