Abstract
A memory system may include: a memory device that operates using a first voltage received from a host and suitable for storing a value of operation information, and waking up from a sleep state in response to a request of the host; and a controller that operates using a second voltage received from the host, and suitable for selectively resetting the memory device according to a result obtained by checking a value of operation information of the memory device, when waking up the memory device in a sleep state according to a request of the host.
Claims17
A memory system comprising:
- a memory device that operates using a first voltage received from a host, wherein memory device is suitable for storing a value of operation information, and waking up from a sleep state in response to a request of the host;
- and
- a controller that operates using a second voltage received from the host,
- wherein the controller is suitable for checking the value of operation information stored in a storage region having a volatile characteristic and selectively resetting the memory device according to the value of operation information when the memory device wakes up from the sleep state.
An operation method of a memory system which includes the memory system includes a memory device and a controller, comprising:
- operating the memory device using a first voltage received from a host;
- and
- operating the controller using a second voltage received from the host,
- wherein the operating of the controller comprises:
- checking operation information stored in a storage region having a volatile characteristic of the memory device when the memory device wakes up from a sleep state according to a request of the host;
- and
- selectively resetting the memory device according to a result of the checking of the operation information.
