Verification of NAND Flash Controller

NAND structure-based Flash memory-made SSDs are turning more popular than HDDs in several applications notably in consumer microelectronics devices and enterprise memory storage devices. The NAND controller is the heart of this system. It acts as a bridge for communication between the host system (usually the Personal Computer system) and the NAND Flash memory storage device. Unarguably, it can be said that it is an essential part of the NAND flash-based memory device and it helps to manage the directory containing file systems. The controller is also accountable for managing system features like wear levelling, error code correction (through ECC), and garbage data collection. With Flash memory devices growing larger in storage space and smaller in area or form-factor, the NAND controller design is converting to a smarter one and complex one, too. Notably, this outline is developed to determine a way to check the features and functionalities that the controller residing into the NAND Flash memory controller provides. To do so, the structured verification approach is used which is based on SV/System Verilog
