DATA PROCESSING SYSTEM AND METHOD FOR ACCESSING HETEROGENEOUS MEMORY SYSTEM

A data processing system (120) and method for accessing a heterogeneous memory system (120) are provided. The heterogeneous memory system (120) includes a memory module (200) and high bandwidth memory (300) including a processing-in-memory circuit (321) combined with a memory controller (114). The memory controller (114) is configured to detect a data array required for an arithmetic operation from a memory module (200) or the high bandwidth memory (300) by using a border index value when the arithmetic operation is performed by the processing-in-memory circuit (321) of the high bandwidth memory (300) and generate a memory module command set and an high bandwidth memory (300) command set (530) using physical address spaces respectively designated in the memory module (200) and the high bandwidth memory (300).
