interface MemoryCacheInterface in Drupal 8

Defines an interface for memory cache implementations.

This has additional requirements over CacheBackendInterface and CacheTagsInvalidatorInterface. Objects stored must be the same instance when retrieved from cache, so that this can be used as a replacement for protected properties and similar.
