Commonly used Error Correcting Codes We know error correcting codes are parameterized as (n,k,d) codes. I wanted to know the values of these parameters for some commonly used error correcting codes in computer memories or in DRAMs, etc.

I just wanted to see some values for these parameters, used in real life applications.
I'm sure this greatly varies according to the application and the specific code in use.

Though not for DRAMs, maybe this will give you some insights:


  For CDs encoding, a (28,24)-Reed Solomon code is used.
  For DVDs, it is a (208,194)-Reed Solomon code.


Symbols are over $GF(2^8)$, that is, 8 bits per symbol.  The notation is $(n,k)$-ReedSolomon for a linear $[n,k,d]$ code ($k$ being the dimension). RS is an MDS code and has $d=n-k+1$.
