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
