The distribution of RAM failure over time is different. Most failure of RAM tend to be in the first few days or even hours. After that the rate drops to a very low value for the next few years. In other words a long warranty time won't cause alot of cost for the manufacturer nor benefit customers much. But it looks good in advertisment ...
