Description and Features

ONFI PHY block is used to either transmit signal and data to NAND Flash interface or receive the data from NAND Flash by Flash controller IP. MDLL sets the delay time for the control signal of PHY to access to the data in flash during the suitable period. Please refer to the following diagram for an overview of ONFI PHY.
