An operation method of a host configured to control a storage device includes receiving, from the storage device, a first response universal flash storage (UFS) protocol information unit (UPIU) including first event occurrence information indicating an occurrence of a first exception event, receiving, from the storage device prior to an exception event check cycle elapsing, a second response UPIU including second event occurrence information indicating an occurrence of a second exception event, and preventing processing of the second exception event, based on the second exception event occurring prior to the exception event check cycle elapsing.

Operation method of host configured to control storage device for processing exceptions and operation method of storage system including host and storage device

Disclosed is an operation method of a storage device which includes a write booster buffer and normal storage. The operation method includes writing first write data received from a host device in the write booster buffer, and selectively performing a flush operation on write booster buffer, in which the first write data stored in the write booster buffer are flushed to the normal storage, based on a device temperature of the storage device. Memory cells included in the write booster buffer are configured to store 'n' bits (n being a natural number), and memory cells included in the normal storage are configured to store “m” bits (m being a natural number more than n).

Storage device, operation method of storage device, and operation method of host device

A method of processing exception events for a storage device includes generating, by the storage device, a first exception event alert comprising a first value and a second value, where the first value indicates generation of exception events and the second value indicates attributes of the exception events, and transmitting, from the storage device, the first exception event alert to a host device.
