Abstract
A data processing system may include a host including a host memory and a first map manager and a memory system including a controller having a second map manager and a memory device suitable for storing system data. When the host provides a first mode request to the memory system, the memory system may provide the system data to the host in response to the first mode request and may deactivate the second map manager in response to the first mode request, and the host may store, in the host memory, the system data provided from the memory system, and may activate the first map manager when providing the first mode request.
Claims20
A data processing system comprising:
- a host including a host memory and a first map manager;
- and
- a memory system including a controller having a second map manager and a memory device suitable for storing system data,
- wherein the host is suitable for providing a first mode request to the memory system,
- wherein the memory system is suitable for:
- providing the system data to the host in response to the first mode request;
- and
- deactivating the second map manager in response to the first mode request, and
- wherein the host is further suitable for:
- storing, in the host memory, the system data provided from the memory system;
- and
- activating the first map manager when providing the first mode request.
An operating method of a data processing system, comprising:
- providing, by a host, a first mode request to a memory system;
- deactivating, by the memory system, a second map manager in the memory system in response to the first mode request;
- providing, by the memory system, the host with system data stored in a memory device in the memory system, in response to the first mode request;
- storing, by the host, the system data provided from the memory system in a host memory in the host;
- and
- activating, by the host, a first map manager in the host when providing the first mode request.
A data processing system comprising:
- a memory device configured to store system data;
- a host including a second control unit configured to provide a second mode request and an operational request along with a logical address;
- and
- a controller configured to control the memory device to perform an operation based on the logical address in response to the second mode request and the operational request, and update the system data stored in the memory device according to the operation,
- wherein the host further includes a first control unit configured to provide a first mode request,
- wherein the controller is further configured to provide system data from the memory device to the host in response to the first mode request,
- wherein the host further includes a host memory configured to buffer the system data provided from the controller,
- wherein the first control unit is further configured to provide an operational command along with a physical address based on the buffered system data,
- wherein the memory device is further configured to perform the operation based on the physical address in response to the operational command, and
- wherein the first control unit is further configured to:
- update the buffered system data according to the operation;
- and
- control the memory device to update the system data stored therein based on the buffered system data when providing the second mode request.
