HYBRID MEMORY MODULE AND SYSTEM AND METHOD OF OPERATING THE SAME

A memory module comprises a volatile memory subsystem configured to coupled to a memory channel in computer system and capable of serving as main memory for the computer system, a non-volatile memorysubsystem providing storage for the computer system, and a module controller coupled to the volatile memory subsystem, the non-volatile memory subsystem, and the C/A bus. The module controller is configured to control intra-module data transfers between the volatile memory subsystem and the non-volatile memory subsystem. The module controller is further configured to monitor C/A signals on the C/Abus and schedule the intra-module data transfers in accordance with the C/A signals so that the intra-module data transfers do not conflict with accesses to the volatile memory subsystem by the memory controller. 一种内存模块包括：易失性内存子系统，用于耦合到计算机系统中的内存通道且能够充当计算机系统的主内存；非易失性内存子系统，其为计算机系统提供存储装置；和模块控制器，其耦合到易失性内存子系统、非易失性内存子系统和C/A总线。模块控制器用于控制在易失性内存子系统和非易失性内存子系统之间的模块内数据传送。该模块控制器进一步用于监视C/A总线上的C/A信号，且根据C/A信号调度模块内数据传送，使得模块内数据传送不与内存控制器对易失性
