title: How to find vendor name from JEDEC id?
body: <p>I would like to get the manufacturer name from JEDEC ids. Here is an example of some ids.</p>
  
  <pre><code>JEDEC ID:7F 7F 7F 7F 7F 51 00 00
  JEDEC ID:80 2C
  JEDEC ID:80 CE
  JEDEC ID:AD 00 00 00 00 00 00 00
  JEDEC ID:CE 01 09 13 45 67 5E F4
  JEDEC ID:CE 01 09 13 47 7A 3E 5A
  </code></pre>
  
  <p>I found this <a href="http://www.idhw.com/textual/chip/jedec_spd_man.html" rel="nofollow">list</a> of manufacturer ids from JEDEC, but I’m not sure if this ids match to my ids and how to connect them correctly.</p>
  
  <p>For example:</p>
  
  <p>If I look at the JEDEC id <code>CE 01 09 13 47 7A 3E 5A</code>, the first Byte <code>CE</code> is equal to <code>11001110</code>. If I compare this value with the JEDEC <a href="http://www.idhw.com/textual/chip/jedec_spd_man.html" rel="nofollow">list</a>, I get Samsung as Vendor. This is correct for the hardware.</p>
  
  <p>But for example the Byte value <code>80</code> from JEDEC id <code>80 CE</code> is missing in the <a href="http://www.idhw.com/textual/chip/jedec_spd_man.html" rel="nofollow">list</a>. Also I cannot find the vendor for <code>7F 7F 7F 7F 7F 51 00 00</code>. Additional to that I don’t know when to use which Byte value from the JEDEC <a href="http://www.idhw.com/textual/chip/jedec_spd_man.html" rel="nofollow">list</a> (Byte 1, Byte 2, ...) In guess <code>01 00 00 00</code> is <em>AMD</em> and <code>00 00 01 00</code> is <em>Camintonn Corporation</em>. But in my case I haven’t any leading zeros. How should I know when to use the second Byte value?</p>
  
  <p>Any idea how to get the vendor name from the ids? Are there any rules?</p>
