Abstract: There is provided an operation method of a memory system which includes a host and a storage device, and the operation method includes allocating a portion of a host memory included in the host for a host memory buffer to be used by a controller of the storage device, setting a set feature command such that the host memory buffer is enabled, setting a retention command including information about a response speed of the host memory buffer, selecting an operation mode of the host memory buffer, based on the retention command, and selecting one of a plurality of power states, which the controller supports, based on a performance objective of the operation mode of the host memory buffer.

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: An operation method of a storage device configured to communicate with an external device through an interface channel includes receiving an indicator of a first throttling level of a plurality of throttling levels from the external device, setting a first operation parameter based on a throttling predefined table (PDT) including a relationship between the plurality of throttling levels and a plurality of throttling performances, such that the interface channel has a first throttling performance from among the plurality of throttling performances, the first throttling performance corresponding to the first throttling level, receiving a first input/output (I/O) request from the external device through the interface channel having the first throttling performance caused by the setting of the first operation parameter, and processing a first operation corresponding to the first I/O request through the interface channel having the first throttling performance.
