Semiconductor device

摘要

The present invention has an object of providing a high-speed, low-cost, and user-friendly information processing system that can ensure scalability of memory capacity. The information processing system is configured to include an information processing device, a volatile memory, and a nonvolatile memory. By serially connecting the information processing device, the volatile memory, and the nonvolatile memory and reducing the number of connection signals, processing speed is increased while maintaining the scalability of memory capacity. When transferring data of the nonvolatile memory to the volatile memory, error correction is performed, thereby improving reliability. The information processing system including the plurality of chips is configured as an information-processing system module in which the chips are alternately stacked and arranged, and wired by a ball grid array (BGA) or by bonding between the chips.
