Typical Data Retention for

Nonvolatile Memory

Definition

Data retention refers to the ability of a memory bit to retain its data state over long periods of time

regardless of whether the part is powered on or powered off.

Freescale Semiconductor guarantees a minimum data retention life in its product specification (generally

10 to 20 years). In practice, our technologies are capable of producing much longer lifetimes than the

specified minimum. To give a better representation of the data retention life that can be achieved for most

parts under nominal conditions, Freescale Semiconductor also provides a typical value in the product

specification.

Freescale Semiconductor defines typical data retention by de-rating the intrinsic data retention capability

of a technology to a normalized use condition.
