hello:

   

I used s34ml02G100 before , i fond a new  ic " S34ml02g200 " is similar to it

   

My question is  

   

1  what’s the main difference between these tow IC?
2  Which ECC type ( 1bit ecc /528byte  or  4bit /528 byte)  should I applicated on each ic  ?
3  Can I use 1bit ecc/ 528byte on  s34ml02G200 ?

   

looking forward your reply! thanks

I'm sorry nobody answered your first posting to the NAND forum.

  • The ML-1 family is 4x nm SLC NAND that requires 1 bit of ECC correction power per 528B.
  •     
  • The ML-2 family is 3x nm SLC NAND that requires 4 bits of ECC correction power per 528B.
  •    
   

>> 3  Can I use 1bit ecc/ 528byte on  s34ml02G200 ?

   
        
  • No, the ML-2 family requires 4 bits of ECC correction power per 528B.

Let me know if you have more questions.

Those two different chips have different memory specifcations, ecc specifications, and are not related to PSoC 4 BLE development 🙂

   

Try reading these two documents and inferring the information you need:
