Technology approaches - especially in terms of Information Technology - have significant importance when Knowledge Management is assessed. However, the manner of managing knowledge generates a gap in the quality of its use. Generated knowledge is appreciated, by Knowledge Management Systems, like a database and, in other hand, like memory processes by Knowledge Based Systems. In this paper the core question is the difference between technology for Knowledge Management Systems and Organizational Memory Systems. Specific cases were reviewed, aiming to explain and elicit specific features from each kind of system in order to help to choose the better Information Technology facilities, in Knowledge Management concerns. As a conclusion, the most important feature, about this choice, is still the human affair. Either, Knowledge Management Systems and Organizational Memory Systems need an understanding of the human capabilities in order to be a right choice and enhance the implantation process.
