Table 2-3: Data Retention

Note 1: Data retention refers to the ability of a memory bit to retain its data state over a period of time after the

data is written in NAND Flash regardless of whether the part is powered on or powered off.

A data retention failure is when there is at least 1 bit of data that cannot be read or is read incorrectly.

Note 2: NAND Flash suppliers refer to JEDEC JESD47 & JESD22 for Data Retention testing.

Based on the information provided by NAND Flash suppliers, ATP targets Data Retention as above table for

reference.
