ONFI4.2 also includes other errata related to the ONFI4.1 specification. To enable higher IOPS multi-plane operations, addressing restrictions related to multi-plane operations are relaxed. The BGA-252b four channel package is introduced which has a smaller footprint than the existing BGA-272b four channel package. Published in February of 2020, ONFI 4.2 extends NV-DDR3 I/O speeds to 1333MT/s, 1466MT/s and 1600MT/s. ONFI5.0 also includes other errata related to the ONFI4.2 specification. New smaller footprint BGA-178b, BGA-154b and BGA-146b packages are added. With the NV-LPDDR4 interface, an optional Data Bus Inversion (DBI) feature is defined. A new NV-LPDDR4 lower power interface is introduced with speeds up to 2400MT/s. Published in May of 2021, ONFI5.0 extends NV-DDR3 I/O speeds up to 2400MT/s.
