1. Cycling performance for products identified by process letter KB (previous products were specified with 1

million cycles at 25 °C).

2. The write cycle endurance is defined for group of four bytes located at addresses [4*N, 4*N+1, 4*N+2,

4*N+3] where N is an integer. The Write cycle endurance is defined by characterization and qualification.

3. 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 the Byte Write, the Page Write or the Write

Identification Page, refer also to Section 5.1.5: ECC (Error Correction Code) and Write cycling

1. The data retention behavior is checked in production, while the data retention limit defined in this table is

extracted from characterization and qualification results.

2. For products identified by process letter KB (previous products were specified with a data retention of 40

years at 55°C).
