Is a 4-Gbit DDP OneNAND device from Numonyx composed of two 2-Gbit 2KB page dice stacked together, the device is equipped with two DataRAMs, and two-plane NAND Flash memory array, These two component enables simultaneous program of 4KiB ( CONFIG_MTD_ONENAND_2X_PROGRAM) Cheers, Enric > > Thank you, > Kyungmin Park > > On Thu, May 6, 2010 at 8:22 PM, Enric Balletbò i Serra > <eballetbo@xxxxxxxxx> wrote: >> Hi, >> >> 2010/5/6 Kyungmin Park <kyungmin.park@xxxxxxxxxxx>: >>> Hi, >>> >>> Can you add this statement at below the code?
