Bueno, finalmente me dieron la respuesta ...
que han pasado por más de 50 enlace relacionado con memcache, el mejor y único vínculo que da cómo implementar memcache en su proyecto es
http://www.codeproject.com/script/Articles/ArticleVersion.aspx?aid=96698&av=163627
y para el conocimiento teórico consulte el siguiente enlace

He creado el documento pequeño echar un vistazo antes de empezar a Memcache
/// difference between set and add and replace
/// add property do not use to add key which is already exist in memcache
/// set use to overwite the key if that is already exist in memcache
/// if key already exist ,replace property can replace it other wise not,where else set property use to replace if key already exist other wise it will add new key in the memcache
///Important
///
/// if u are fetching the key which do not exist in memcache it will return null,as well if u are fetching the key whose value is null in memcache it will return null
/// so avoid inserting the key with null value
///
///If you simply want to avoid key collision between different types of data, simply prefix your key with a useful string. For example: "slash_1", "pradeep_1".
///
///
///
/// FlushAll() method use to remove(Flush) every thing from memcache
///
/// Stats() gives every information about the memcache like total items,connections,pId etc.....
/// difference between increment, decrement
///
/// to use Increment or Decrement first u need to store counter by StoreCounter method else u will get null
///
/// difference between GetMultiple and GetMultipleArray
///
///GetMultiple gives you the object with there key and GetMultipleArray gives you the object not the key
