摘要：A memory controller includes a first error detection code generator forgenerating a first error detection code for data received from a host, a controller to

write the data and the first error detection code to nonvolatile memory and to read thedata and the first error detection code from the nonvolatile memory, an error detectorto perform an error detection based on the data and the first error detection code thatare read from the nonvolatile memory, a second error detection code generator togenerate a second detection error code based on the data read from the nonvolatilememory, and a mismatch code generator to generate a mismatch code signaling thepresence of an error in the data, wherein either the second error detection code or themismatch code is selected based on the error detection and sent to the host.
