Abstract
A memory system with high capacity and high performance, having memory units with a type of 3D NOR flash or 3D NAND flash. The memory system comprises a plurality of logic units connected with one another in series to form a chain. Each of the logic units is a logic unit number (LUN) device having an identifier 'LUN ID', and comprises a control circuit. The control circuit communicates with a host controller through a common interface utilizing an ONFI bus and a sideband bus, and the control circuit of a corresponding logic unit may communicate with a control circuit of an adjacent logic unit through the sideband bus. The control circuits of the logic units cooperate with a host controller to perform an enumeration for the identifier “LUN ID” of each of the logic units.
