Abstract: An operating method for a memory system including a host and a memory system. The operating method may include; communicating maximum power information from the memory system to the host, communicating power table information and battery information from the host to the memory system in response to the maximum power information, and controlling power consumption by a component of the memory system in response to a maximum consumption power value, wherein each of the power table information and the battery information is related to a battery associated with the memory system and operating in accordance with battery steps, the power table information includes a number of entries including a first entry and a second entry, the first entry is related to a first battery step among the battery steps and associated with a first maximum consumption power value, the second entry is related to a second battery step among the battery steps and associated with a second maximum consumption power value, and the maximum consumption power value controlling power consumption by the component of the memory system is one of the first maximum consumption power value and the second maximum consumption power value.

Abstract: A storage device includes a storage controller and a non-volatile memory including a first memory region including first memory cells having a first data retention time and a second memory region including second memory cells having a second data retention time that is shorter than the first data retention time. Based on an erase request being received from a host in a first operation mode, the storage controller determines whether to switch from the first operation mode to a second operation mode. The storage controller programs program data in a memory region selected from the first memory region and the second memory region in the first operation mode, and the storage controller programs the program data in only the first memory region in the second operation mode.

Abstract: Provided are a storage system including a host and a storage device and a method of operating the storage system. The method includes, when a response time of the storage device is greater than a threshold time, stopping, by the storage system, a previous mode and entering a recovery mode, when a state of a connection between the host device and the storage device is a link down state, resetting, by the storage system, the connection between the host device and the storage device, transmitting, by the host device, a recovery signal to the storage device, and performing, by the storage device, storage recovery.
