Redis solves the same problem, while offering way more features. In terms of speed, Redis is in the same area. Memcached is also a key-value store (quote from the official site "Memcached is an in-memory key-value store for small chunks of arbitrary data"). I've been slowly using Redis more and more over the past 6 months, and as an heavy memcached user, i can tell you that i don't really see a need for both, might as well take advantage of the useful features Redis as to offer on top of the "basic" Memcached-like stuff.

Redis is persistent, replicated storage, isn't it? No matter what buzzwords they use on their site, Memcached is a volatile cache, it should never be used to store otherwise irretrievable information. I know, people use it for stuff like session storage, but that's really not a good use case for it. I don't want to attack Redis, so there is no need to defend it. Maybe memcached-like behavior is one of its many features, but I personally like Memcached exactly because of its simplicity.
