endurance(1)

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.

Write

cycle(2)

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).
