Abstract
An exemplary storage controller for controlling data access of a storage device includes a control circuit and a soft decoder. The control circuit is utilized for reading data from the storage device to obtain readout data. The soft decoder is coupled to the control circuit, and utilized for performing a soft decoding operation upon the readout data to generate decoded data. The soft decoder may be a low density parity check (LDPC) decoder, a block turbo code (BTC) decoder, or a convolutional turbo code (CTC) decoder. The storage device may be a flash memory device.
Claims20
A storage controller for controlling data access of a storage device, comprising:
- a control circuit, configured for reading data from the storage device to obtain readout data;
- and
- a soft decoder, coupled to the control circuit, for performing a soft decoding operation upon the readout data to generate first decoded data.
A storage control method for controlling data access of a storage device, comprising:
- reading data from the storage device to obtain readout data;
- and
- performing a soft decoding operation upon the readout data to generate first decoded data.
A system comprising:
- a storage device;
- and
- a storage controller, coupled to the storage device, for controlling data access of the storage device, wherein a data signal transmitted from the storage device to the storage controller carries soft information derived from the storage device.
