STRUCT NAND_MEMORY_ORGANIZATION(9)

🎀 struct nand_memory_organization(9) 🎀

Okay bestie, welcome to the Kernel API Manual entry for struct nand_memory_organization — literally the Memory organization structure, and it's giving blueprint energy. No cap, this is the vibe check for how NAND memory is laid out. 💅✨

---

💖 NAME 💖

struct nand_memory_organization — the Memory organization structure. It's iconic, it's organized, and it's here to hold all the layout details. 🫶

🌈 SYNOPSIS 🌈

       struct nand_memory_organization {
           unsigned int bits_per_cell;
           unsigned int pagesize;
           unsigned int oobsize;
           unsigned int pages_per_eraseblock;
           unsigned int eraseblocks_per_lun;
           unsigned int max_bad_eraseblocks_per_lun;
           unsigned int planes_per_lun;
           unsigned int luns_per_target;
           unsigned int ntargets;
        };

🌸 Members 🌸

Every field is here, bestie — no skipping, no summarizing, periodt. 💖

• bits_per_cell — number of bits per NAND cell. Literally how many bits each cell holds. ✨
• pagesize — page size. That's the page size, no cap. 🎀
• oobsize — OOB area size. Yep, the out-of-band area's size. 🦋
• pages_per_eraseblock — number of pages per eraseblock. The way that pages stack inside an eraseblock is iconic. 💅
• eraseblocks_per_lun — number of eraseblocks per LUN (Logical Unit Number). LUN said what it said. 👑
• max_bad_eraseblocks_per_lun — maximum number of bad eraseblocks per LUN. Bad blocks get a max, fr fr. 💀
• planes_per_lun — number of planes per LUN. Planes within a LUN, slay. 🌈
• luns_per_target — number of LUN per target (target is a synonym for die). Iykyk. 🎲
• ntargets — total number of targets exposed by the NAND device. The whole target count, periodt. ⭐
