Understanding Use Cases

EDGE to Core Architecture

– Distributed versus Centralized

Data:

– How data is written, read, kept

– What are the operational conditions (use profile)

Interface / Form Factor:

– BGA; Plug-in Board; Removable

– UFS; e.MMC; SD; NVMe.

Data Retention

Power-on data retention

–Read disturb, cold data are concerns

–Controller + FW are the ideal solution

Power-off data retention

– JEDEC Standard is 10 years for fresh device – 1 year for fully cycled

–Data retention is impacted by how much the device was cycled
