Abstract: Disclosed is a computing system which includes a storage device and a host. The storage device may include a nonvolatile memory, and the host may control the storage device based on a physical address of the nonvolatile memory and may send an asynchronous event request command to the storage device. The storage device may monitor the nonvolatile memory and may send an asynchronous event request corresponding to the asynchronous event request command to the host based on the monitoring result. The asynchronous event request may include requesting another command from the host based on the monitoring result. In some aspects, the host may send an erase command for erasing to erase a selected memory block of the nonvolatile memory to the storage device. In response, the storage device may send an erase pass response or an erase delay violation response to the host in response to the erase command.

Abstract: A flash memory based storage system and operating method are provided. A host of the storage system requests an erase unit size from the storage device and uses a multiple of the erase unit size to partition a logical address. Each host block may be assigned a state selected from a group of states including: an open state in which an erase unit of the storage device is allocated, a write state in which data is written at an erase unit of the storage device, a close state in which a write operation is no longer performed, and an invalidate state in which valid data of a host block is invalidated.
