An electronic system includes: a key value storage device, configured to transfer user data, the key value storage device including: a non-volatile memory array accessed by a key value address, an interface circuit, coupled to the non-volatile memory array, configured to receive a key value transfer command, a volatile memory, coupled to the interface circuit and the non-volatile memory array, configured to reduce a number of copies of the user data in the non-volatile memory array, and a device processor, coupled to the interface circuit, configured to manage the non-volatile memory array, the volatile memory, and the interface circuit by a key value index tree, including a key value translation block, to access the user data.

Electronic system with storage management mechanism and method of operation thereof

According to one embodiment, a computer system includes a host computer, and a storage device coupled to the host computer. The host computer has a user-space device driver of the storage device in a user space of a host operating system (OS). The user-space device driver is configured to handle I/O operations to and from the storage device based on an application running on the host computer.

Method for application-aware interrupts management

A system and method for enabling an application () and a storage device () to be more aware of each other may include a computer (), a processor (), and a memory () as well as the storage device (). An application () stored in the memory may communicate with a user space device driver (). The user space device driver () may include a Mode Configure Module () to receive an application profile () from the application () and an Application Aware Module () to receive I/O commands () from the application () and place them in command queues () according to the application profile (, and). The I/O commands () may then be sent to the storage device ().
