US 10,871,915 B2 · Data processing system and operating method thereof

Abstract

A data processing system and a method of operating the same may include a host system and a memory system. The host system may include a host memory and a host controller, and the memory system may include a memory controller and a nonvolatile memory device. The memory controller may include a data attribute determination circuit and a memory selection circuit. The data attribute determination circuit may be configured to determine an attribute of write data received from the host controller. The memory selection circuit may be configured to select, based on the determined attribute of the write data, any one of the host memory and the nonvolatile memory device as a location where the write data is to be stored.

Dependent claims

A data processing system comprising:

a host system including a host memory and a host controller;
and
a memory system including a memory controller, a buffer memory and a nonvolatile memory device,
the memory controller comprising:
a data attribute determination circuit configured to determine an attribute of write data based on a size of the write data received from the host controller;
a reference provider configured to provide a first reference size and a second reference size;
and
a memory selection circuit configured to select the host memory when the size of the write data is smaller than the first reference size, and to select the nonvolatile memory device or the buffer memory, by comparing the size of the write data with the second reference size, when the size of the write data is equal to or larger than the first reference size.
