}

ZNS-TLC-class NAND timing + geometry, in CONTROLLER CLOCK CYCLES. Engineering-realistic ratios (read : program : erase ≈ 1 : 10 : 100); the table is DATA for the flash architect to correct, and every measurement re-derives from it.

Fields

channels: u32

Independent data-bus channels.

dies_per_channel: u32

Dies per channel — the parallelism that lets one die erase while others read.

planes_per_die: u32

Planes per die (multi-plane program/erase; reads serialize on the die here).

pages_per_block: u32

Pages per erase block.

zone_pages: u64

Pages per zone (append-only unit; a zone reset erases its blocks).

t_r: u64

Page read (sense) latency.

t_prog: u64

Page program latency.

t_bers: u64

Block erase latency (~10³× a read — the tail source we schedule away).

data_cycles: u64

Channel cycles to move one page of data in/out.

suspend_window: u64

Max cycles a program/erase may be SUSPENDED to let a read through (Tier-B budget).

ldpc_retry_worst: u64

Bounded worst-case extra latency of a soft-LDPC read-retry (Tier-B envelope).

Implementations

impl FlashTimings

pub fn zns_tlc() -> Self

A host-managed ZNS-TLC-class part: 8 channels × 8 dies (enough die depth to hide the sense latency behind the channel data-out), 100× erase.

pub fn pslc_fast() -> Self

A pSLC fast-path part: faster sense/program/erase, tighter suspend — the crown-tier medium where erases fit in per-die idle gaps with room to spare.

pub fn n_dies(&self) -> u32

Total independent dies.

pub fn read_latency_bound(&self) -> u64

The worst-case read latency the tier promises: sense + data-out, plus (Tier B) a budgeted suspend and a bounded LDPC retry. A read never exceeds this.

Trait Implementations

impl Clone for FlashTimings

fn clone(&self) -> FlashTimings

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FlashTimings

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
