SEMICONDUCTOR DEVICE

摘要

It is possible to provide a user-friendly information processing system which can assure extension of a memory capacity with a high speed at a low cost. The information processing system includes an information processing device, a volatile memory, and a nonvolatile memory. The information processing device, the volatile memory, and the nonvolatile memory are connected in series and the number of connection signals is reduced, so as to assure extension of the memory capacity and increase the speed. When transferring data from the nonvolatile memory to the volatile memory, error correction is performed to improve reliability. The information processing system having these chips is formed as an information processing system module in which the chips are mutually layered on one another and wired by a ball grid array (BGA) and bonding between the chips.
