SEMICONDUCTOR MEMORY DEVICE AND COMPUTER SYSTEM INCLUDING THE SAME

摘要

A semiconductor memory device includes a first memory block of a first type of memory; and a second memory block of a second type of memory having a different type from the first type. A first address region of the first memory block and a second address region of the second memory block are included in the same address domain. Each of the first and second memory blocks is accessed by an address signal including an address of the address domain, and the second memory block is a nonvolatile memory.
