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

An electronic system includes: a key value storage device, configured to transfer user data, including: a non-volatile memory array, 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 transfer the user data with the interface circuit or 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 to access the user data; and wherein: the interface circuit, connected to a device coupling structure, configured to receive the key value transfer command; and the device processor is configured to address the non-volatile memory array, the volatile memory, or both concurrently based on a key value transfer.
