DESCRIPTION¶

This struct defines the timing requirements of a SDR NAND chip. These information can be found in every NAND datasheets and the timings meaning are described in the ONFI specifications: www.onfi.org/~/media/ONFI/specs/onfi_3_1_spec.pdf (chapter 4.15 Timing Parameters)

All these timings are expressed in picoseconds.
