FPGA Implementation of NOR Flash Storage Controller

Flash storage memory devices are Nand and NOR types which are widely used in data storage application in computers and solid states drives. Flash are nonvolatile and electrically erased and reprogrammed. A flash memory controller (or flash controller) manages the data stored on flash memory and communicates with a computer or electronic device. When the system or device needs to read data from or write data to the flash storage, it will communicate with the flash controller. Flash controller is used to control programming and erasing operation of flash memory storage. FPGA builds reconfigurable environment for flash memory controller which helps in generation of exact timing specifications of flash chip. NAND Flash does not support in place updates to overcome this disadvantage of NAND storages proposed design works on NOR flash memory.
