Abstract
A memory module comprises dynamic random access memory (DRAM), Flash memory, and a module controller. The module controller is configured to receive data to be transferred from the DRAM to the Flash memory, compute first cyclic redundancy check (CRC) codes for the data, and write the data into the Flash memory. The module controller is further configured to read the data from the Flash memory, compute second CRC codes for the data read from the Flash memory, and transfer the data to the DRAM. The module controller is further configured to compare the second CRC codes with the first CRC codes to determine one or more erroneous data bits in the data read from the Flash memory, read a data segment of the data from the DRAM that include the one or more erroneous data bits, correct the one or more erroneous data bits in the data segment, and write the data segment back into the DRAM.
