Memory system including memory module memory module and operating method of memory module

Abstract

A semiconductor memory module may include a random access memory, a nonvolatile memory, a buffer memory, and a controller configured to execute a reading operation on the buffer memory in response toan activation of a control signal. The controller may be further configured to execute a flush operation of storing first data, which are stored in the random access memory, in the nonvolatile memory,according to a result of the reading operation.

Description

[0001] This application claims priority to Korean Patent Application No. 10-2018-0035270 filed with the Korean Intellectual Property Office on March 27, 2018, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Embodiments of the inventive concept relate to a semiconductor memory, and more particularly, to a memory system including a memory module, a memory module, and a method of operating the memory module. Background technique [0003] Semiconductor memory uses semiconductor devices to store data. Semiconductor memories include volatile memories such as dynamic random access memory or static random access memory and nonvolatile memories such as flash memory, phase change memory, ferroelectric memory, magnetic memory, resistive memory, and the like. [0004] Generally, volatile memory supports high-speed random access and is used as the main memory of computing systems such as personal computers, servers, or workstations. ...
