Abstract
A NAND controller for interfacing between a host device and a flash memory device (e.g. a NAND flash memory device) fabricated on a flash die is disclosed. In some embodiments, the presently disclosed NAND controller includes electronic circuitry fabricated on a controller die, the controller die being distinct from the flash die, a first interface (e.g. a host-type interface, for example, a NAND interface) for interfacing between the electronic circuitry and the flash memory device, and a second interface (e.g. a flash-type interface) for interfacing between the controller and the host device, wherein the second interface is a NAND interface. According to some embodiments, the first interface is an inter-die interface. According to some embodiments, the first interface is a NAND interface. Systems including the presently disclosed NAND controller are also disclosed. Methods for assembling the aforementioned systems, and for reading and writing data using NAND controllers are also disclosed.
