redis - can you replicate from a master that persists to disk to slaves that are in-memory databases only?

I'm wondering if Redis is the right tool to use for the following scenario / use case:

I need to replicate data from a "master" database running on a server that will have a hard drive... to "slave" locations / servers that only have ram?

I'm currently reading through the Redis manual and also trying out some of the tutorials. But I haven't come across anything yet that explicitly answers my question. If you have any experience with Redis, your input would be appreciated.

Thanks.
