What kind of AdSense format is this?

Hello,

I just realized some interesting AdSense ad format on ehow.com.
Both the text sizes and also the js/html code seems to be interesting.

Check these page for example ():
http://www.ehow.com/facts_7926076_apache-mysql-server-50-errors.html

Check the AdSense ad under the "Usage" section of the article.

And this is the code for it:

					<div id="DMINSTR" type="adimpression" data-type="adTracking" 
			name="&amp;adunit_id=ca-ehow_336x280&amp;ad_unit_type=CNT&amp;ad_unit_network=GAP&amp;revenue_basis=CPC&amp;ad_position=-&amp;revenue_tag=cpu_computer_troubleshooting">
		<div id="GoogleAdsense336x280" class="Module"></div>
		<script>
			googleAds.addAdUnit({
				priority : 2,
				adUnitId : 'GoogleAdsense336x280',
				google_ad_channel : 'cpu_computer_troubleshooting,text,suggested7',
				google_ad_client : 'ca-ehow_336x280',
				google_max_num_ads : '4',
								google_hints : '',
								google_image_size : '336x280'
			});
		</script>

	</div>

Code (markup):

How can I create such ad blocks?
