SEMICONDUCTOR MEMORY SYSTEM HAVING SEMICONDUCTOR MEMORY DEVICES OF VARIOUS TYPES AND A CONTROL METHOD FOR THE SAME

摘要

Disclosed are a semiconductor memory system having semiconductor memory devices of various types and a control method for the same. A semiconductor memory system according to an embodiment of the present invention comprises a plurality of semiconductor memory devices; and a memory controller for controlling the read-out of data programs for the plurality of semiconductor memory devices and data from the plurality of semiconductor memory devices; wherein at least two of the plurality of semiconductor memory devices differ from each other in terms of one or more of the following: the number of bits of data programmed in memory cells, the degree of integration, the manufacturer, whether they are synchronised, and whether or not encoded data is stored.
