SEMICONDUCTOR MEMORY DEVICE INCLUDING NON-VOLATILE MEMORY AND CACHE MEMORY AND COMPUTER SYSTAM HAVING THE SAME

A semiconductor memory device including a non-volatile memory and a cache memory and a computer system comprising the same are disclosed. The cache memory according to an embodiment of the present invention comprises: a first storage area including a plurality of data blocks for storing data; and a second storage area for including m number of ECC blocks corresponding to n number of data blocks, wherein each of the first and the second storage areas includes non-volatile memory cells. At least one ECC block stores first information indicating an ECC parity for correcting an error bit of the corresponding data block and a position of the corresponding data block.
