What I tried to do with robocore is have a number of subsystems dedicated to particular modalities such as vision, touch, hearing, smell and so on. Each of these modalities operates in a semi independent and self organised way, and their function is to create stable abstractions from the raw data of sensory experience. So what you end up with are learned representations (you could call them symbols or neural groups) which can act as building blocks for experience.
Each of the main modality specific subsystems is linked to a central hub or switching mechanism (think of it as a big telephone exchange). This hub can connect the partial representations into multi-modal constellations which might be called percepts. These percepts can be formed by association in a sort of bottom up way, but they can also be recalled by higher level systems so that you have bi-directionality. A memory in this architecture is a kind of reconstruction of the original experience from the representational jigsaw. This is a rather Freudian way of thinking about memory, since it's an active reconstruction which could be subject to alteration over time in the light of new experiences. From an information storage point of view it's also fairly efficient. To recall a memory the hub switches are set appropriately which lights up those areas within particular modalities close to the level of direct experience.
