Abstract
A semiconductor package includes: memory devices that are stacked one on another; and an inter-layer channel for communication between the memory devices, wherein each memory device includes: a data pad; a memory core; a data input/output circuit that inputs/outputs data through the data pad; an inter-layer channel transfer circuit that transfers a read data transferred from the memory core to the inter-layer channel or transfers a data inputted through the data input/output circuit to the inter-layer channel; an inter-layer channel reception circuit receiving the data of the inter-layer channel; a read error correction circuit correcting an error of the data transferred from the inter-layer channel reception circuit to produce an error-corrected data and transfers the error-corrected data to the data input/output circuit; and a write error correction circuit generating a parity data to be stored in the memory core based on the data transferred from the inter-layer channel reception circuit.
