Linux can mount a filesystem on a flash device. In that case, just use 
the filesystem as a fast cache. Tugela cache can use the filesystem as a 
cache and therefore could use the flash device as it's cache. there 
would be no need to tweak memcache for that.

The filesystem would still do read/write caching in RAM. You might also 
mount the flash device as a high-priority swap device and use tmpfs with 
Tugela cache.
