Abstract
A storage device optimizes block closure in a memory device and maintains quality of service provided to a host device. The storage device receives commands from a host device and writes host data to a block in the memory device in a first state. When the storage device has not received a host write command for a host write idle time period, the storage device transitions to a second state, performs background operations at a first rate, and writes data to the block. When the storage device has not received a host read command or a host write command for a complete idle time period, the storage device transitions to a third state based, performs background operations at a second rate, and writes data to the block. The storage device uses the transitions between the states to maintain quality of service provided to the host device.
