title: Embedded System and Serial Flash wear issues
body: <p>I am using a serial NOR flash (SPI Based) for my embedded application and also I have to implement a file system over it. That makes my NOR flash more prone to frequent erase and write cycles where having a wear level Algorithm comes into picture. I want to ask few questions regarding the same:</p>
  
  <p>First, is it possible to implement a Wear Level Algorithm for Nor flash, if yes then why most of the time I find the solutions for NAND Flash and not NOR Flash?</p>
  
  <p>Second, are serial SPI based low cost NAND flashes available, if yes then kindly share the part number for the same.</p>
  
  <p>Third, how difficult is it to implement our own Wear Level algorithm?</p>
  
  <p>Fourth, I have also read/heard that industrial grade NOR Flashes have higher erase/write cycles (in millions!!), is this understanding correct? If yes then kindly let me know the details of such SPI NOR Flash, which may also lead to avoiding implementation of wear level algorithm, if not completely then since I'm planning to implement my own wear level algorithm, it might give me a little room and ease in certain areas to implement the wear level algorithm.</p>
  
  <p>The constraint to all these point is cost, I would want to have low cost solution to these issues.</p>
  
  <p>Thanks in Advance</p>
  
  <p>Regards</p>
