    S25FL164K: P/E cycles in different scenarios

    frhic_3865271

      Hi all

       

      I previously asked a question about how multiple program operations on the same page affect flash wear out (S25FL164K: Do multiple program operation on the same page reduce data integrity?)

       

      However, some things are still unclear to me. So I thought I'll ask a follow-up question with some examples.

       

      (At the start of each Scenario all Sectors of the flash are in the erased state.)

       

      Scenario 1 (write one page):

      1. Write 0x00 to Page 1 Sector 1
      2. Erase Sector 1

       

      How many P/E cycles? (I think 1)

       

      Scenario 2 (write Page 1 twice):

      1. Write 0x0F to Page 1 Sector 1
      2. Write 0xF0 to Page 1 Sector 1
      3. Erase Sector 1

       

      How many P/E cycles? (I think 1)

       

      Scenario 2 (write two pages):

      1. Write 0x00 to Page 1 Sector 1
      2. Write 0x00 to Page 2 Sector 1
      3. Erase Sector 1

       

      How many P/E cycles? (I think 1)

       

      I would be glad if someone could confirm my assumptions of the P/E cycles for each scenario.
