1. The Write cycle endurance is defined for groups of four data bytes located at addresses [4*N, 4*N+1, 4*N+2, 4*N+3] where

N is an integer, or for the status register byte (refer also to Section 5.2: Cycling with Error Correction Code (ECC)). The

Write cycle endurance is defined by characterization and qualification.

2. A Write cycle is executed when either a Page Write, a Byte Write, a Write Identification Page or a Lock Identification Page

instruction is decoded. When using those Write instructions, refer also to Section 5.2: Cycling with Error Correction Code

(ECC).
