ONFI I/O is a non-volatile memory interface technology with high bandwidth capabilities, mainly developed for flash storage applications. M31 provides a silicon-proven ONFI I/O in a variety of process nodes, which complies with international Open NAND Flash Interface specification, providing on-die termination (ODT) and supporting ZQ impedance calibration, and can be customized based on customer specifications. The ONFI 6.0, ONFI 5.1, and ONFI 5.0 I/O IP have been silicon-proven at advanced FinFet nodes. In addition, M31 also provides solutions for signal integrity (SI) issues such as FFE and DFE.
